CFexpress Type A Cards Reviewed: 6 Top Picks Tested

CFexpress Type A is a small format with an outsized performance ceiling , fast enough for RAW burst shooting on the Sony A1 and sustained 4K video on the FX3, but only if the card you choose actually delivers on its rated specs under real camera conditions. The format is controlled by Sony’s slot implementation, so compatibility is narrower than SD or CFexpress Type B, and not every card performs equally when the buffer fills.

This guide covers six CFexpress Type A cards across budget and premium tiers, with attention to read/write speeds, sustained write consistency, and capacity trade-offs. For a broader look at the format landscape, the Memory Cards hub covers how CFexpress Type A fits alongside Type B and SD options.

Top Picks

Sony CFexpress Type A 160GB Memory Card (CEAG160T)

The Sony CFexpress Type A 160GB CEAG160T is the baseline card most Sony Alpha shooters default to, and owner reports bear out why. Rated at 800MB/s read and 700MB/s write, this card sits comfortably within the performance envelope the Sony A7S III and A7 IV were tuned to use. Burst shooters report the buffer clears quickly and reliably , fewer instances of the camera slowing mid-sequence compared to lower-tier cards.

The 160GB capacity occupies a useful middle ground. It is large enough for extended RAW shooting sessions or a full day of 4K video without swapping, but not so large that a single card loss becomes catastrophic. Verified buyers on Amazon consistently note this card behaves predictably across firmware updates, which matters more than it might seem , some third-party cards have shown compatibility issues after Sony camera updates.

For most Sony mirrorless shooters who want a reliable, properly-specced card without moving to higher-tier pricing, the case for this CEAG160T is strong.

Lexar 512GB Professional CFexpress Type A Silver 4.0

The Lexar 512GB Professional CFexpress Type A Silver 4.0 is the high-capacity, high-throughput option for videographers working in 8K RAW or photographers running extended back-to-back burst sessions. Rated at up to 1750MB/s read and 1650MB/s write, these speeds reflect the PCIe 4.0 interface rather than the PCIe 3.0 spec that governs most existing Type A cards. That distinction matters: cameras must support PCIe 4.0 to unlock these figures, and current Sony Alpha bodies do not.

In practice, the Lexar Silver 4.0 will run at PCIe 3.0 speeds in today’s camera bodies , which is still fast , but its primary value proposition is forward compatibility. As Sony and other manufacturers release PCIe 4.0-capable bodies, this card will not become the bottleneck. Owner feedback on the 4.0 series is still accumulating, but early verified buyer reports highlight fast offload speeds via compatible card readers, which is itself a workflow advantage regardless of in-camera limits.

The 512GB capacity makes this card particularly well-suited to cinema shooters who need maximum continuous recording time without interruption.

Sony CFexpress Type A 160GB Flash Memory

The Sony CFexpress Type A 160GB Flash Memory card is an earlier-generation Sony card that predates the CEAG160T in the product lineup. The rated speeds are lower than the CEAG160T , owner reports and spec comparisons show this card operating in an older performance tier , which makes it a card to consider carefully rather than assume equivalent to its successor.

Where this card still earns consideration is in proven long-term reliability. It has been in the market longer, which means a larger base of documented owner experience. Photographers who have used it across years of shoots with the A7R IV and A9 II consistently describe it as stable, with no unexpected behavior during extended recording or burst sequences. Sustained write consistency is the attribute most often praised in field reports.

For buyers who place reliability tier above peak throughput and who are not yet shooting formats that stress the upper speed limits, owner consensus supports this card as a dependable workhorse.

Gold II 512GB CFexpress 4.0 Type A Card VPG800

The Sony Gold II 512GB CFexpress 4.0 Type A is Sony’s current high-capacity flagship, VPG800 certified with rated sustained read of 1780MB/s and write of 860MB/s. The VPG800 designation is the relevant spec for video professionals , it guarantees a minimum sustained write floor of 800MB/s, which covers 8K RAW and 12K video workflows on compatible recording devices. That floor matters more than peak ratings for uninterrupted video capture.

Owner reports from FX6 and FX9 users highlight the card’s sustained write consistency during long-form recording. The 512GB capacity supports extended continuous recording without the need to swap cards mid-shoot, which is operationally significant for documentary and event work. Verified buyers working in cinema formats describe this as the card they reach for when the shot cannot be interrupted.

The PCIe 4.0 interface means the same forward-compatibility story applies here as with the Lexar Silver 4.0 , current camera bodies operate the card at PCIe 3.0 speeds, but the card is positioned for the next generation of professional Alpha and FX bodies.

Sony CEA-G80T 80GB CFexpress Type A Memory Card

The Sony CEA-G80T 80GB is the entry point into the CFexpress Type A format from Sony , the smallest capacity in the current lineup and the most accessible price tier. Rated at 800MB/s read and 700MB/s write, it shares the same speed class as the CEAG160T. The only meaningful difference is capacity, which makes it a straightforward decision: 80GB works for shooters who keep sessions short, shoot JPEG alongside RAW, or are picking up a second card for overflow.

Where owner feedback gets specific is in hybrid shooting. Photographers running the Sony A7C or ZV-E1 as a compact travel camera note the 80GB card fills faster than expected when mixing RAW stills with 4K video clips in the same session. That is not a flaw , it is a capacity reality worth understanding before purchase. For shooters who plan primarily around stills or shorter video clips, the card performs exactly as the spec sheet promises.

The CEA-G80T makes most sense as a backup card for shooters who already own a larger-capacity Type A, or as a primary for those who offload cards frequently.

Lexar 256GB Professional CFexpress Type A Silver 4.0

The Lexar 256GB Professional CFexpress Type A Silver 4.0 offers the same PCIe 4.0 architecture as its 512GB sibling in a capacity that suits most single-day shooting scenarios. Rated at up to 1750MB/s read and 1650MB/s write, it carries the same forward-compatibility positioning , current Alpha bodies will not saturate these speeds, but the card will not become obsolete when they do.

For photographers who shoot high-resolution stills in volume , A1 or A7R V burst sequences in RAW , 256GB hits a practical sweet spot. It is large enough to run most sessions without swapping and small enough to manage in a multi-card workflow without concentrating too much footage on a single card. Community consensus among A1 shooters on forums points to this capacity tier as the most operationally balanced for event and sports work.

Buying Guide

Read Speed vs. Write Speed: Which Number Actually Matters

Both figures appear on the box, but they serve different workflows. Read speed governs how fast images and footage transfer from the card to a computer , the number that affects your post-session workflow. Write speed governs how fast the camera can commit data to the card during shooting, which directly controls whether the buffer clears fast enough to keep pace with continuous burst or sustained 4K video capture.

For still photographers shooting RAW bursts, sustained write speed is the number to evaluate. A card with high peak write but poor sustained write will slow the camera mid-sequence as the buffer backs up. For video, the VPG certification tier provides a more reliable indicator than rated peaks, since it guarantees a minimum floor under sustained load conditions.

Understanding VPG Ratings for Video Work

Video Performance Guarantee ratings , VPG200, VPG400, VPG800 , define the minimum sustained write speed under worst-case thermal and load conditions. VPG200 supports most 4K video workflows. VPG400 covers higher-bitrate 4K recording. VPG800, carried by the Sony Gold II 512GB, is required for reliable 8K RAW and cinema-format continuous recording.

If sustained video recording is the primary use case, the VPG floor is a more meaningful spec than the headline read number on the front of the package. A card rated at a high peak read speed but without VPG certification provides no guaranteed floor for video write performance.

PCIe 3.0 vs. PCIe 4.0 in Current Camera Bodies

All current Sony Alpha and FX camera bodies with CFexpress Type A slots operate at PCIe 3.0 speeds. PCIe 4.0 cards , including the Lexar Silver 4.0 series and the Sony Gold II , will function in these bodies but will be capped at PCIe 3.0 throughput in-camera. The benefit of PCIe 4.0 cards today is faster card-reader offload speeds when using a PCIe 4.0-compatible reader, and readiness for future camera bodies that implement PCIe 4.0 slots.

Buyers who want to maximize current in-camera performance without paying a premium for forward compatibility should evaluate whether the speed delta at the card reader justifies the difference for their workflow.

Capacity Planning for Burst and Video Workflows

The practical capacity question depends heavily on file size per shot and recording format. A Sony A1 shooting compressed RAW at 50fps fills storage differently than an A7C shooting JPEG-priority sports. For memory card capacity planning, the useful framing is sessions between offloads, not total shooting volume.

For video-primary shooters, 4K XAVC-S at high bitrates consumes roughly 60, 100GB per hour depending on camera model and codec settings. An 80GB card covers a short shoot. A 256GB or 512GB card supports a full day of mixed shooting. Having two cards of a given capacity and rotating them is standard practice in professional workflows.

Camera Compatibility and Firmware Considerations

CFexpress Type A cards only work in cameras with a dedicated Type A or dual-format SD/Type A slot. Current Sony bodies with Type A compatibility include the A1, A7 IV, A7S III, A7R V, A7CR, A9 III, FX3, FX30, ZV-E1, and select FX cinema bodies. No other manufacturers currently produce Type A-compatible bodies at consumer scale.

Sony-branded cards have a documented track record of stable behavior across firmware updates on these bodies. Some third-party CFexpress Type A cards have shown edge-case compatibility issues after major firmware revisions. Checking current firmware release notes before purchasing third-party cards is a reasonable precaution for shooters on professional workflows.

Frequently Asked Questions

Do CFexpress Type A cards work in cameras that only have an SD card slot?

No. CFexpress Type A requires a dedicated Type A slot or a dual-format slot that explicitly supports the CFexpress Type A standard. The card is physically smaller than a standard SD card and uses a different electrical interface entirely. Sony Alpha bodies with Type A compatibility list the slot specification in the body’s technical documentation.

What is the difference between the Sony CEAG160T and the older Sony 160GB Flash Memory card?

The CEAG160T is Sony’s current-generation 160GB Type A card with updated controller firmware and a stronger track record of compatibility with recent Alpha firmware releases. The older 160GB Flash Memory card operates at a lower performance tier based on its original spec sheet and represents an earlier phase of Sony’s Type A card development. For new purchases, the CEAG160T is the stronger choice at the same capacity.

Will a PCIe 4.0 CFexpress Type A card like the Lexar Silver 4.0 damage or cause issues in a PCIe 3.0 camera body?

No. PCIe 4.0 cards are backward compatible with PCIe 3.0 slots. The card will operate at PCIe 3.0 speeds inside current Sony camera bodies without any risk of damage or instability. The performance benefit of PCIe 4.0 is available today through compatible card readers, and will transfer to in-camera performance when Sony releases PCIe 4.0-capable bodies.

How much capacity do I actually need for a full day of shooting on a Sony A7S III?

The A7S III shooting 4K XAVC S-I at 60fps generates roughly 160GB per hour at the highest bitrate setting. A 256GB card covers a roughly ninety-minute continuous recording window at that setting. For most hybrid shooters mixing video with stills, 256GB to 512GB covers a full day without mid-session swaps. The 256GB Lexar Silver 4.0 and Sony Gold II 512GB are the options most aligned with that workflow.

Is VPG800 certification necessary for 4K video, or only for 8K?

VPG800 is not required for standard 4K video. Most 4K recording on Sony Alpha bodies is covered by VPG200 or VPG400 at typical bitrate settings. VPG800 is specifically designed for sustained 8K RAW and high-bitrate cinema formats on Sony FX bodies and compatible cinema recorders. For photographers and videographers shooting 4K on Alpha bodies, the Sony CEAG160T or Sony CEA-G80T provide adequate write floor coverage without requiring the VPG800 tier.
