Does SanDisk 64GB Extreme PRO CFast 2.0 Memory Card work w/ Canon 5D SR and at 350mb/s write speed?

[jgerrish]

I see there are now CF cards that support up to 350MB/sec write speeds.  I was thinking of getting one for my 5DSR, but not sure if CFast 2.0 cards are support and support those write speeds on the 5DSR.

I don't believe the 5DS R uses CFast CF cards.

Not likely going to be an upgrade unless you need new cards. Fastest write speed looks like 101 MB/S
