Angelbird has introduced their new generation of CFexpress Type A memory cards for Sony Alpha and Cinema Line cameras: the AV PRO SE CFexpress A v4 in a single 200GB capacity, and the AV PRO CFexpress A v4 in 400GB, 800GB, and 1600GB capacities. Both lines share a maximum read speed of 1870 MB/s, and Angelbird’s Stable Stream technology, with the AV PRO models reaching sustained write speeds of up to 1600 MB/s. So, let’s take a closer look at them!

We’ve covered a fair amount of Angelbird’s storage lineup recently, including the AV PRO SD V30 MK2 SD cards, the next-generation AV PRO microSD V30 built for drones and action cameras, and a broader conversation with the company on AI, memory shortages, and the state of camera innovation.

With the recently announced Sony FX5, which we reviewed here if you missed it, and the introduction of Sony X-OCN RAW, fast CFexpress Type A memory cards will be necessary if you want to record internally in the highest codecs/formats. To solve that problem, Angelbird is back with CFexpress A v4 memory cards that deliver faster read and write speeds, so you can record internally in any format with peace of mind.

Two lines, four capacities

In total, Angelbird’s fourth generation of CFexpress Type A memory cards consists of four products:

• The AV PRO SE CFexpress A v4, with a single model and a capacity of 200GB.
• The AV PRO CFexpress A v4 in capacities of 400GB, 800GB, and 1600GB.

Let’s start by saying that all cards are claimed to be compatible with the Sony A1, A1 II, A9 III, A7R V, A7 IV, A7S III, FX5, FX3/FX3A, FX2, FX30, and FX6.

Both card lineups share similarities, including a maximum read speed of 1870 MB/s, a sustained read speed of up to 1700 MB/s, a new-generation controller, a reduced internal design, and reworked firmware. The cards feature the company’s Stable Stream technology, which is meant to keep write speeds consistent throughout a recording rather than only at the start, and to hold up as the card fills, ages, and runs background wear-leveling and garbage collection.

Also, according to Angelbird, the cards feature an “advanced integrated thermal management architecture, engineered to maintain consistent performance as camera temperatures rise during intensive, high-load operations”.

As always with Angelbird memory cards, they are also shock/dust/moisture/X-ray/magnet and temperature-proof.

So, what’s the difference between the two memory card lines?

Angelbird AV PRO SE CFexpress A v4 – features

The AV PRO SE CFexpress Type A v4 is the “budget-friendly” option with VPG200 certification for photography and hybrid creators. This card has a sustained write speed of 500MB/s, which can capture footage up to 8K, but it is not designed for recording in RAW. If you are constantly switching between stills and video and don’t want to break the bank, this is the way to go.

The AV PRO CFexpress Type A v4 400/800/1600GB cards carry VPG400 and VPG800 certifications and target higher-end video production and the most demanding photography workloads.

The 400GB model has a sustained write speed of 1000 MB/s, the 800GB model is 1500 MB/s, and the 1600GB version maxes out at 1600 MB/s.

If you plan to shoot in X-OCN RAW format with the Sony FX5, you’ll need VPG400-certified CFexpress Type A memory cards. All three Angelbird AV PRO CFexpress Type A v4 models can sustain the large amount of data produced by 16-bit X-OCN recordings.

Price and availability

The Angelbird AV PRO SE CFexpress A v4 is available now for $199/€226.81. The AV PRO CFexpress Type A v4 will set you back $399.99/€361.26 for the 400GB model, $599/€756.22 for the 800GB model, and $899.99/€1008.32 for the 1600GB version.

All cards come with a 3-year limited warranty and Angelbird’s in-house data recovery service (activation required within 30 days of purchase), and support firmware updates via the Angelbird Card Reader PKT CFexpress A.
