Sony doesn’t have a monopoly on CFexpress Type-A cards, that’s for sure. We have brands like ProGrade and Lexar as well as a couple more to give us options but Sony is heavily invested in the standard for one reason or another, presumably because most Sony’s new high-end Alpha cameras all support CFexpress Type-A and require it for shooting scenarios like S&Q. But as late, only 320GB was the largest we’ve had for CFexpress Type-A from any brand. I personally only use a 160GB LEXAR Professional GOLD CFexpress Type-A card, but that changes now.
For $1399 for 1920GB and $749 for 960GB, the Sony TOUGH CFexpress Type-A cards are the largest storage capacity CFexpress Type-A cards in the market. Rated for 800MB/s reads and 700MB/s writes, these drives are made for speed at their form factor. CFexpress Type-A operate at PCIexpress 3.0 x1 speeds for PC comparison.
CFexpress Type-A cards are usually marketed for their endurance and Sony is living up to the name TOUGH branding as their cards are rated for -10*C up to 70*C operating temperatures. They’re also rated to endura shocks and bends as well as survive splashes of water and drops in the dirt.
