This one has slower Sustained Write Speed of 805 MB/s. Has anyone used it?

if you bump the size up to 650GB you get the faster speeds

Thanks John. The 650G is not on sale. I guess I need to wait a bit.

800MB/s isn't horribly slow. XQD cards tended to be about 400MB/s, and lots of the early CFE-b cards were about 1000MB/s. the fast cards are about 1400-1600MB/s but note that most of the fastest cards don't actually see that benefit because you max out how fast you run in camera based on how the camera works, and you max out in most situations on your computer due to USB so typical speeds on the computer max out around 1000MB/s anyways.

so twice as good as XQD

i would have no concerns getting the G4 version of the delkin power as an economy choice

XQD isn't even 400MB/s, the sustained speeds are about 260-300MB/s if I recall correctly.
