Shawn C. Steiner from Explora tested the new new generation of CFexpress Type A cards from OWC:

• OWC 960GB for $389 at Amazon, BHphoto, Adorama.
• OWC 480GB for $287 at Amazon, BHphoto, Adorama.

Shawn writes:

Looking at OWC’s documentation, you will see that the Atlas Pro cards are tested to offer 400 MB/s sustained write speeds. That is more than enough for all the cameras that currently support Type A cards.
There is one note with speed. Technically, the Atlas Pro cards are only rated to VPG200. This is more than enough for even the top high frame rate options of the FX3 and FX6 even though they might not be rated at the top speeds of competing cards. The CFexpress 4.0 technology more than makes up for this with real-world performance. Per OWC, these cards are designed for sequential writes since that is how cameras operate.
Testing it myself through my go-to tool Blackmagic Disk Speed Test and using a USB4 reader on an M3 MacBook Pro, I was able to get consistent results of >1500 MB/s for both write and read speeds. Using the same test for a last-gen CFx Type A card I was only getting half that. You will potentially halve the amount of time it takes to get your media off your cards and onto your drive.
