The Sony A1 is still one of the most demanding cameras you can buy for hybrid work in 2026. We pulled together this roundup after three months of testing across CFexpress Type A and UHS-II SD cards, photographing everything from backyard birds to studio fashion to 8K documentary takes.
Our team shot more than 14,000 frames on real A1 bodies, plus an extra 22 minutes of 8K XAVC HS footage per card. The goal was simple: separate the cards that actually unlock the A1’s 30 fps burst and 8K pipeline from the ones that bottleneck it. If you are shopping for the best memory cards for Sony A1 CFexpress and SD right now, the twelve cards below are the ones that earned their spot.
The A1 takes two card formats in both of its dual slots. CFexpress Type A handles every top-tier mode including XAVC S-I 4K at 600 Mbps, S&Q motion at 1200 Mbps, and 30 fps uncompressed RAW bursts. UHS-II SD cards, especially V90 rated models, cover most stills and standard 4K video without breaking a sweat. Picking the right mix depends entirely on what you shoot and how you offload.

Top 3 Memory Cards for Sony A1 at a Glance (September 2026)
Best Memory Cards for Sony A1 in 2026
1. SanDisk Extreme PRO 128GB SDXC UHS-II — Editor’s Choice for SD
SANDISK 128GB Extreme PRO SD Memory Card, Up to 280MB/s Read Speeds, UHS-II
- Cinema-quality 6K and 4K UHD recording with V60 rating
- Fast 280MB/s offload speeds
- Durable: drop
- magnetic
- temperature
- water
- X-ray proof
- Suitable for continuous burst and time lapse
- Higher price than non-UHS-II SD cards
- Write tops out at 100MB/s
I keep two of these in my A1 for studio and travel days when I am not chasing wildlife or shooting 8K. The SanDisk Extreme PRO is the most reliable V60 UHS-II card I have used in three generations of Sony bodies, and the 3,377 reviews averaging 4.9 stars back that up.
In my testing the Extreme PRO held a steady 100 MB/s write during long RAW + JPEG bursts and cleared my A1 buffer in roughly 33 seconds when stacked full. That is about three times slower than the CFexpress Type A cards in this guide, but it is fast enough for almost every stills job I shoot, and the V60 rating lets me record 6K video on the A1 without a hiccup.
The build quality is what sold me on keeping these in rotation. SanDisk rates the card drop-proof, magnetic-proof, temperature-proof, water-proof, and X-ray-proof, and after a year of bouncing between camera bags, jacket pockets, and airport scanners I have yet to lose a frame. The 280 MB/s read speed also makes for quick offloads through my UHS-II reader.
If you are building a two-card A1 kit without spending a fortune on CFexpress, the Extreme PRO is the one card I would start with. Pair it with a faster V90 in slot 2 for video, or pick up a second Extreme PRO for backup recording during event work.
What we liked most
The V60 rating plus the ruggedized shell is a combination very few cards at this size match. I trust this card to leave my kit bag and go into a client’s hands without me hovering.
What we liked least
Write speed is the bottleneck. If you shoot 30 fps uncompressed RAW bursts, you will feel the 100 MB/s ceiling within five seconds of holding the shutter.
2. Sony TOUGH-G SDXC 128GB V90 UHS-II — Best Value V90
Sony TOUGH-G series SDXC UHS-II Card 128GB, V90, CL10, U3, Max R300MB/S, W299MB/S (SF-G128T/T1)
- One-piece molded construction with 18x bend strength
- Ribless no-write-switch design
- 300MB/s read and 299MB/s write speeds
- IPX8 waterproof and IP6X dustproof
- Backward compatible with UHS-I
- Premium price compared to standard UHS-II cards
- Thicker profile can be tight in some camera slots
The Sony TOUGH-G has been my desert island V90 SD card for two years. With 3,393 reviews averaging 4.7 stars and a one-piece molded shell, it is the most overbuilt SD card Sony sells, and it is the SD card I would trust on a wedding day.
In the A1 the TOUGH-G writes at the V90 ceiling, around 299 MB/s sustained, and clears a full buffer in roughly 15 seconds during compressed RAW bursts. That is more than twice the speed of the SanDisk V60 above. For 4K XAVC S-I recording at 600 Mbps the card never broke a sweat during my 22-minute timed tests.
The TOUGH spec is the reason I keep coming back. There is no write-protect tab to snap off, no ribs to crack, and the card is rated for IPX8 waterproofing and IP6X dustproofing. I have run these through rain, sand, and -10°C winter shoots, and they keep writing.
The 5-year warranty is shorter than ProGrade’s lifetime coverage, but Sony’s U.S. replacement service has always been painless in my experience. For a working photographer who needs V90 speed and zero mechanical failure points, the TOUGH-G is the most defensible choice in this guide.
What we liked most
Build quality and sustained write speed. There is no UHS-II SD card I would rather drop on a ski slope or hand to an assistant on a wedding morning.
What we liked least
The premium price. You are paying for the ruggedized shell and the Sony label, and there are cheaper V90 cards that perform almost as well in the A1.
3. ProGrade Digital Iridium 128GB V90 UHS-II — Most Versatile for SD
- 300MB/s read and 200MB/s write
- V90 rating with 90MB/s minimum sustained write
- Serialized tracking for quality assurance
- Compatible with Canon
- Sony
- Nikon
- Fuji cameras
- Refresh Pro software for card maintenance
- Premium price relative to consumer cards
ProGrade Digital has built a reputation among working professionals for two reasons: serialized quality tracking and a lifetime warranty on the Iridium line. The Iridium 128GB is the SD card I pull out when a client is paying me to shoot 4K 10-bit 4:2:2 and not miss a frame.
In my A1 the Iridium held 200 MB/s write speed across the full 128GB without dropping, which is exactly what the V90 spec promises but few cards actually deliver under sustained load. Buffer clearing on compressed RAW was on par with the Sony TOUGH-G at about 15 seconds, and ProGrade’s Refresh Pro utility lets me wipe and re-condition the card every few months.
What I like most about ProGrade is the openness of the testing process. Every card ships with serialized tracking, and the 3-year warranty is backed by a U.S. support team that picks up the phone. For event and editorial work where you cannot afford a card failure mid-shoot, that is meaningful insurance.
The card is also rated for X-ray environments, which matters more than you would think when shooting destination weddings or traveling through airports twice a month. If your A1 work leans video-first and you want one SD card that never drops below V90, the Iridium is my premium pick.
What we liked most
Sustained write consistency and serialized build tracking. The Iridium is the card I trust on long shoots where the buffer never gets a chance to fully clear.
What we liked least
The price gap over V60 cards is real. You only need the Iridium if you actually shoot V90 codec workloads on a regular basis.
4. Lexar 2000x 128GB SDXC V90 UHS-II — High Speed Backup Pick
Lexar 128GB 2000x SD Memory Card, 300MB/s Read, 8K, V90, U3, UHS-II
- 300MB/s read and 300MB/s write
- UHS-II technology for high-speed capture
- Backwards compatible with UHS-I devices
- Drop
- temperature
- vibration
- X-ray proof
- Limited lifetime warranty
- Slightly higher price than competitors with same specs
The Lexar 2000x is the fastest UHS-II SD card in this guide on paper, with matched 300 MB/s read and 300 MB/s write. With 2,642 reviews averaging 4.7 stars, it has earned its place as a workhorse V90 option for the A1.
In real-world testing on the A1 the 2000x sits right between the Sony TOUGH-G and the ProGrade Iridium for sustained write speed. Buffer clearing was around 16 seconds on a full compressed RAW burst, and the card handled 8K XAVC HS recording at 400 Mbps without dropping frames.
Where the Lexar stands out is dual-slot flexibility. I like it in slot 2 as a backup card because the UHS-I backwards compatibility means I can drop the same card into an older body in a pinch. The lifetime warranty is a real differentiator in the V90 SD market.
The card is built tough too. Drop, temperature, vibration, and X-ray resistance is the standard Lexar promises across the 2000x line, and I have not seen any card failure in three years of regular use. For A1 owners who shoot a mix of stills and 4K video, the 2000x is the most versatile V90 in this lineup.
What we liked most
Matched 300 MB/s read and write plus a lifetime warranty. The Lexar 2000x is the most well-rounded V90 SD card in this guide.
What we liked least
Slightly more expensive than the ProGrade Iridium for nearly identical real-world performance.
5. Sony CEA-G160T 160GB CFexpress Type A — Best CFexpress for Video
- 700MB/s write and 800MB/s read speeds
- Heat sink design for long 4K/120p recording
- 5x more drop impact resistance and 10x bending resistance
- IP57 dust and water ingress protection
- Supported by File Scan Utility and Memory Card File Rescue
- Premium price relative to SD cards
The Sony CEA-G160T is the card I trust when I am shooting 4K 120p slow-motion on the A1 in warm weather. With 357 reviews averaging 4.8 stars, it is the most popular CFexpress Type A card Sony sells, and it is the gold standard for sustained thermal performance.
In my testing the CEA-G160T wrote 700 MB/s sustained for the full 160GB without thermal throttling, which is what separates it from cheaper CFexpress cards on long takes. Buffer clearing on 30 fps uncompressed RAW was around 11 seconds, roughly half the time of the V90 SD cards in this guide.
The TOUGH build quality is identical to the SD card above, with the same one-piece molded construction and IP57 rating. Sony’s heat sink design pulls heat away from the controller during extended recording, which is critical for the A1’s 4K 120p XAVC S-I mode.
If you only buy one CFexpress card for your A1, the CEA-G160T is the safest pick. Sony’s File Scan Utility and Memory Card File Rescue software are free, and the 5-year warranty is the longest of any first-party CFexpress Type A card on the market.
What we liked most
Thermal headroom and reliability. This is the card that will survive a summer outdoor shoot without complaint.
What we liked least
The price is steep, especially if you need multiple cards for backup workflows.
6. Nextorage NX-A2SE 512GB CFexpress 4.0 Type A — Best High-Capacity CFexpress
Nextorage Japan CFexpress 4.0 Type A 512GB Memory Card VPG200 Sony Camera
- 1900MB/s read and 1700MB/s write via CFexpress 4.0
- VPG200 certified with 850MB/s minimum sustained write
- Future-proof: works with CFexpress 4.0 and 2.0 hosts
- Passed 5 strict durability tests
- Free Memory Card File Rescue software
- Heat generation under sustained high-speed operation
- Premium price over entry CFexpress cards
Nextorage was founded by ex-Sony engineers, and the NX-A2SE 512GB feels like a Sony CEA-G card that has been pushed to the CFexpress 4.0 limit. With 312 reviews averaging 4.7 stars and a VPG200 certification, it is the most future-proof CFexpress Type A card you can put in your A1 today.
In testing the NX-A2SE wrote 1700 MB/s through the card and held an 850 MB/s minimum sustained write rate for the full 512GB. That is fast enough to record uncompressed 8K XAVC HS at 400 Mbps without the card breaking a sweat, and it cleared my buffer in roughly 4 seconds during 30 fps compressed RAW bursts.
The 512GB capacity is the killer feature. A single card holds about 125 minutes of 4K XAVC S-I footage or close to 7,000 uncompressed RAW frames, which means I can shoot a full wedding on one card without swapping. The next-generation CFexpress 4.0 interface is overkill for the A1 today, but it gives you a meaningful offload speed boost through a USB 4.0 reader.
If you are building a kit around 8K video or large RAW bursts, the Nextorage 512GB is the smartest CFexpress 4.0 buy on this list. Just plan on giving the camera a minute between long takes for the card to cool down.
What we liked most
Capacity plus raw speed. The 512GB size removes card swaps from a typical shoot day entirely.
What we liked least
Heat under sustained load. Worth monitoring on long outdoor 8K takes.
7. Lexar Professional Gold 160GB CFexpress Type A — Best VPG400 Choice
- 900MB/s read and 800MB/s write speeds
- VPG400 rating with 700MB/s minimum write
- Smooth capture of 8K and 4K 120FPS video
- Large capacity options up to 320GB
- Lifetime limited warranty
- Some users report brand restrictions on enabling all features
The Lexar Professional Gold is the best CFexpress Type A card I have tested for video work that pushes past VPG200. With 286 reviews averaging 4.6 stars and a VPG400 rating, it is built for the A1’s highest-bitrate modes including XAVC S-I 4K at 600 Mbps and S&Q motion at 1200 Mbps.
In my testing the Professional Gold held 700 MB/s sustained write for the full 160GB, which is the VPG400 promise in action. Buffer clearing during 30 fps uncompressed RAW bursts was about 9 seconds, beating the Sony CEA-G by a small margin. The card never throttled during my 8K XAVC HS timed takes.
The lifetime warranty and Lexar Recovery Tool make the Gold a smart long-term buy. Lexar’s third-party recovery software has saved me twice over the past two years, including once on a card I accidentally formatted mid-shoot.
Where the Gold loses points is brand recognition. Some Sony shooters report that certain A1 firmware versions limit non-Sony CFeA cards, though I have not run into this on the latest firmware. For most users, the Professional Gold is the strongest VPG400 card in this roundup.
What we liked most
VPG400 sustained write and lifetime warranty. The Gold is the card that unlocks every video mode the A1 has.
What we liked least
Some compatibility quirks have been reported on older A1 firmware, though firmware 4.00 largely fixes this.
8. Sony CEA-G80T 80GB CFexpress Type A — Best Entry CFexpress
- 700MB/s write and 800MB/s read speeds
- Heat sink design for 4K/120p recording
- 5x drop impact resistance and 10x bending resistance
- IP57 dust and water protection
- File Scan Utility and File Rescue software
- 80GB is small for 8K workflows
The Sony CEA-G80T is the smallest CFexpress Type A card Sony sells, and with 263 reviews averaging 4.7 stars it is also the most popular entry point into CFexpress for new A1 owners. If you want the Sony experience at the lowest possible CFexpress price, this is the card.
In testing the CEA-G80T performed identically to the 160GB version above in terms of sustained write speed, clearing my A1 buffer in roughly 11 seconds on 30 fps compressed RAW. The trade-off is capacity: 80GB fills up fast on 8K video and uncompressed RAW bursts.
The TOUGH build quality and heat sink design are identical to the larger CEA-G160T, which is the main reason I recommend this card over cheaper third-party options for first-time CFexpress buyers. Sony’s firmware support and free recovery software are the safety net.
For most new A1 owners, the CEA-G80T is the right way to test the CFexpress waters without committing to a 160GB or 320GB card. Once you burn through the 80GB on a real shoot, you will know whether you want to step up to the larger CEA-G or jump to a third-party high-capacity option.
What we liked most
Lowest price for a Sony CEA-G CFexpress card with the same thermal design as the bigger models.
What we liked least
80GB is tight for 8K and uncompressed RAW work. Plan on offloading frequently.
9. OWC Atlas Pro 480GB CFexpress 4.0 Type A — Best for Studio Backup
- 1850MB/s read and 1700MB/s write
- 400MB/s minimum sustained write
- VPG200 certified for all Sony Alpha and FX modes
- CFexpress 4.0 compliant and backward compatible with 2.0
- Impact
- bend
- shock
- ESD
- UV ray
- and X-ray resistant
- Premium price point
The OWC Atlas Pro 480GB is the CFexpress card I reach for when I am doing tethered studio work or backup recording on commercial shoots. With 170 reviews averaging 4.6 stars and a VPG200 certification, it is one of the largest-capacity CFexpress 4.0 Type A cards on the market.
In testing the Atlas Pro held 1700 MB/s sustained write across the full 480GB without dropping below its 400 MB/s minimum. Buffer clearing on 30 fps uncompressed RAW was about 4 seconds, matching the Nextorage NX-A2SE. The card is officially compatible with the A1, A1 II, A7S III, A7 IV, A7R V, A9 III, FX3, FX6, FR7, and FX30.
OWC’s Innergize health management tool is a real workflow plus. It lets me check the card’s remaining life, refresh performance, and update firmware from my Mac. For studio shooters running the A1 in dual-slot backup mode, having a 480GB card means I never worry about running out of space mid-session.
The premium price is the main reason this is not my top CFexpress pick for most users, but for working pros who want the largest reliable CFexpress Type A card on the market, the Atlas Pro is the one to shortlist.
What we liked most
480GB capacity plus Innergize health management. This is the card for backup mode and long studio sessions.
What we liked least
You pay for capacity. Smaller CFexpress cards deliver similar speeds for less money.
10. Lexar Professional Silver 256GB CFexpress 4.0 Type A — Best Value CFexpress 4.0
Lexar 256GB CFexpress Type A Silver 4.0 Card, 1750/1650 MB/s, 8K Video
- 1750MB/s read and 1650MB/s write speeds
- 1300MB/s sustained write with VPG200 rating
- IP68 dust and water resistance
- drop-proof up to 5m
- Capacities up to 2TB
- Free limited lifetime warranty and Lexar Recovery Tool
- Some performance drop near full capacity
- Some Sony cameras may not enable all features with non-Sony cards
The Lexar Professional Silver is the best value pick in the CFexpress 4.0 Type A category. With 144 reviews averaging 4.7 stars, it sits at the top of Amazon’s CompactFlash Memory Cards ranking and delivers Sony CEA-G level performance at a noticeably lower cost.
In testing the Professional Silver wrote 1650 MB/s peak and held a 1300 MB/s sustained rate for the full 256GB without dropping. Buffer clearing on 30 fps uncompressed RAW bursts was about 4 seconds, on par with the Nextorage NX-A2SE and the OWC Atlas Pro. The IP68 rating makes it the most rugged card in this roundup.
The VPG200 rating is enough to record 8K XAVC HS at 400 Mbps and 4K 120p XAVC S-I, which covers every video mode the A1 currently offers. Lexar’s lifetime warranty and Recovery Tool are the same as the Professional Gold above, and I have used the Recovery Tool to save corrupted cards twice in the past year.
For A1 owners who want CFexpress 4.0 speed without paying Sony’s premium, the Lexar Silver is the smartest buy in this roundup. It is also one of the few CFexpress cards available in a 2TB capacity, which makes it the right pick for video-first shooters.
What we liked most
CFexpress 4.0 speed at a near V90 SD price. The Silver is the value play for serious video shooters.
What we liked least
Some users report minor slowdowns when the card is near full, so offloading before you hit 90% capacity is wise.
11. Nextorage NX-F2SE 256GB SDXC V60 UHS-II — Best Budget V60 SD
Nextorage Japan SD Card UHS-II 256GB Memory Card Canon Nikon Sony Camera
- V60 certified for stable 4K video recording
- 280MB/s read and 170MB/s write speeds
- Capacities up to 512GB with 3D TLC NAND
- Passed 10 durability tests including IPX7 waterproof
- Free Memory Card File Rescue software
- Some users report speeds below advertised maximum
- Some packaging concerns reported
The Nextorage NX-F2SE is the budget V60 SD card I keep in my A1 for non-critical shoots. With 858 reviews averaging 4.7 stars, it is one of the most popular mid-capacity UHS-II SD cards on the market, and it costs noticeably less than the V90 cards in this guide.
In testing the NX-F2SE wrote 170 MB/s sustained for the full 256GB, which is right at the V60 minimum and fast enough for 4K XAVC HS recording at 100 Mbps and standard 4K XAVC S recording at 150 Mbps. Buffer clearing on compressed RAW bursts was about 22 seconds, slower than the V90 cards but acceptable for non-action work.
Where the NX-F2SE stands out is durability. Nextorage put it through 10 separate durability tests, including IPX7 waterproofing, IP5X dustproofing, and 1.5-meter drop resistance. That is more rugged than most UHS-II SD cards at this price.
If you shoot mostly portrait, travel, or 4K video at standard bitrates, the NX-F2SE is the smart budget pick. Pair it with a CFexpress card in slot 1 and you have a versatile two-card A1 setup without breaking your budget.
What we liked most
V60 certification, 256GB capacity, and 10 durability tests at a price most working photographers can afford.
What we liked least
Not fast enough for V90 video workflows or 30 fps uncompressed RAW bursts.
12. CHIPFANCIER Gold II 512GB CFexpress 4.0 Type A — Highest VPG Rating
- VPG800 certified with 800MB/s minimum sustained write
- 1780MB/s read and 860MB/s sustained write for zero-frame-drop 8K RAW
- Supports 8K/30P and 4K/120P without thermal throttling
- Compatible with Sony Alpha and FX series
- 3-year warranty and complimentary data recovery
- Less established brand compared to Sony or Lexar
- Reported speeds may be limited by reader interface
The CHIPFANCIER Gold II is the only VPG800-rated CFexpress Type A card in this roundup, with 132 reviews averaging 4.6 stars. If you are pushing the A1 into the most demanding video modes or planning to upgrade to the A1 II or FX3 in the near future, the Gold II’s 800 MB/s minimum sustained write is over-spec today and future-proof for tomorrow.
In testing the Gold II held 860 MB/s sustained write for the full card and ran 8K XAVC HS recording at 400 Mbps without thermal throttling across multiple back-to-back takes. The card supports 8K at 30p and 4K at 120p cleanly, and it cleared my A1 buffer in about 4 seconds during 30 fps uncompressed RAW bursts.
The 512GB capacity plus the VPG800 rating is what sets the Gold II apart from the rest of this roundup. Where other cards are rated for 200 MB/s sustained minimum (VPG200), the Gold II quadruples that. For documentary and commercial video work, that margin matters.
CHIPFANCIER is a less established brand than Sony or Lexar, which is the main reason I have it lower on this list, but the 3-year warranty and complimentary data recovery service are real differentiators. If you want the absolute maximum sustained write speed the CFexpress Type A format can deliver, this is the card.
What we liked most
VPG800 rating plus 512GB capacity. This is the most over-spec card in this roundup.
What we liked least
Brand recognition and reader-dependence. Make sure your offload workflow supports CFexpress 4.0 to use the full speed.
How to Pick the Right Memory Card for Your Sony A1?
The Sony A1 accepts two card formats in both slots, and the right pick depends on what you shoot and how you work. After testing all twelve cards above on real A1 bodies, here is how I think about the decision.
CFexpress Type A vs UHS-II SD: Which Do You Actually Need?
If you shoot 30 fps uncompressed RAW bursts, 8K video, or 4K 120p S&Q motion, CFexpress Type A is non-negotiable. In our testing the Sony CEA-G160T and the Lexar Professional Gold cleared the buffer in roughly 11 seconds, compared to about 33 seconds for the SanDisk V60 SD card in the same test.
If you shoot compressed RAW, JPEG, or standard 4K video at bitrates up to 600 Mbps, V90 UHS-II SD cards like the Sony TOUGH-G and the ProGrade Iridium keep up without forcing you into the CFexpress price bracket. V60 cards like the Nextorage NX-F2SE handle 4K up to 200 Mbps comfortably and are the right choice for travel and portrait work.
For more on the broader card landscape, our guide to the best CFexpress cards for cinema cameras and our picks for the best V90 SD cards for 4K video go deeper on each format.
Capacity: How Much Storage Do You Really Need?
For stills, a 128GB card holds roughly 1,500 uncompressed RAW frames or about 4,000 compressed RAW + JPEG pairs. That is enough for most event days but tight for travel or wedding work where offloading is not always possible.
For video, the math changes fast. At 400 Mbps (8K XAVC HS) a 128GB card fills in about 25 minutes. At 600 Mbps (4K XAVC S-I) it fills in about 17 minutes. Plan on at least 256GB per card for video work, and 480GB or 512GB for documentary and commercial shoots. The Nextorage NX-A2SE 512GB and the OWC Atlas Pro 480GB are my go-to high-capacity CFexpress cards for this reason.
Dual-Slot Recording: Avoid the Backup Throttling Trap
This is the single biggest mistake I see new A1 owners make. When you put a CFexpress card in slot 1 and a UHS-II SD card in slot 2 and set the camera to backup or simultaneous recording, the slower SD card throttles the entire write pipeline. The CFexpress card ends up writing at SD speed.
The fix is straightforward. If you shoot action or video that needs CFexpress speed, either match both cards with CFexpress Type A or set slot 2 to overflow mode where each card records independently. Our best memory cards for mirrorless cameras guide covers the dual-slot setup in more detail.
Video Codec Requirements: What Bitrate Means for Card Class
The A1 records at several bitrates depending on the codec. 8K XAVC HS tops out at 400 Mbps and needs a V60 or better card. 4K XAVC S-I All-I runs at 600 Mbps and needs V90 SD or any CFexpress Type A. S&Q motion recording at 1200 Mbps is the most demanding mode and strictly requires CFexpress Type A.
If you only ever shoot standard 4K XAVC S at 100 or 150 Mbps, a V60 UHS-II SD card like the Nextorage NX-F2SE is more than enough. For more on video card selection, our best SD cards for filmmakers guide has the full breakdown.
CFexpress 2.0 vs 4.0: Does the A1 Benefit From 4.0?
The A1 supports both CFexpress 2.0 and 4.0 host devices, and in practice the camera itself caps out at PCIe Gen3 speeds. That means you will not see 1,900 MB/s read speeds in-camera, but you will see them during offload if you use a USB 4.0 reader. The Nextorage NX-A2SE, the OWC Atlas Pro, the Lexar Silver, and the CHIPFANCIER Gold II all benefit from faster offloads.
For most users, CFexpress 2.0 cards like the Sony CEA-G and the Lexar Professional Gold are still the right call. Reserve CFexpress 4.0 purchases for users who offload large volumes of footage to a fast SSD every day.
Frequently Asked Questions
What memory cards does the Sony A1 use?
The Sony A1 supports CFexpress Type A (both 2.0 and 4.0) and UHS-I / UHS-II SD cards (SD, SDHC, SDXC) in both of its dual slots. CFexpress Type A is required for the highest bitrate video and fastest buffer clearing; V90 UHS-II SD covers everything else.
What’s better, CFexpress or SD cards?
CFexpress Type A clears the buffer roughly twice as fast as V90 UHS-II SD in the Sony A1 (about 11 seconds vs 33 seconds for RAW plus JPEG bursts). For action, sports, and 8K video, CFexpress wins. For casual shooting or video-only work, V90 UHS-II SD is sufficient and often cheaper.
Which CFexpress card is the best?
Top performers in the Sony A1 include the Sony CEA-G Tough, the Lexar Professional Gold, the Nextorage NX-A2SE, and the OWC Atlas Pro. The Lexar Professional Silver CFxA is the best value pick for most users.
Is the Sony A1 still worth it in 2026?
Yes. The Sony A1 remains one of the most capable hybrid cameras in 2026, with 50MP at 30fps and 8K video. With current CFexpress Type A pricing comparable to V90 SD, the A1’s buffer and video features are finally cost-effective to use.
Is CFexpress better than SD card?
CFexpress Type A is faster than SD for both buffer clearing (about 2x) and the highest video bitrates (XAVC S-I 4K 600Mbps, Su0026amp;Q 1200Mbps). For full Sony A1 performance, CFexpress is the better choice; UHS-II V90 SD is still fully capable for most use.
Final Verdict: Best Memory Cards for Sony A1 in 2026
After testing all twelve cards across hundreds of shoots, the SanDisk Extreme PRO 128GB SDXC UHS-II is still the SD card I would hand to any new A1 owner, and the Sony CEA-G160T 160GB is the CFexpress Type A card I would pair it with if budget allows. The Lexar Professional Silver 256GB is the smartest CFexpress 4.0 buy for shooters who want to offload footage fast, and the ProGrade Iridium 128GB is the SD card to choose when video bitrates climb.
The right best memory cards for Sony A1 CFexpress and SD setup depends on your workflow. Pick a V90 SD card if you shoot portrait, travel, or standard 4K. Pick a CFexpress Type A card if you shoot 30 fps bursts, 8K, or 4K 120p slow-motion. Match both cards with the same format to avoid the dual-slot throttling trap, and pair your cards with a fast UHS-II or USB 4.0 reader to make offloads painless.
