It’s not as fast as the Lexar 2000X Lexar Professional 64GB SDXC card, but this kind of speed is more than adequate for all digital cameras, even the Nikon D810 and the Leica S. This card will be put into field use soon for diglloyd photography.
As shown below, the Lexar Professional 1066X Compact Flash 128GB can write at 144 MB/sec and read (download to computer) at 154 MB/sec over the entire capacity.
UPDATE 11 May: I used the Lexar 128GB in the field in the Nikon D810, and it performed flawlessly. It will see a lot more use as my primary card in the field (for my cameras that use CompactFlash).
The Lexar Professional 128GB 1066X Compact Flash is a card for cameras of course, and it requires a separate card reader. So if you’re looking for a fast USB3 thumb drive, check out the OWC Thumb Drive.
