Random corrupt images on cards
on 26 April 2013
I bought two of these to use in my 5D2, 5D3 and 7D and no issues with them at all. Fast read write, well fast enough that continuous shooting is restricted by camera buffers not by slow card writing and that's all that matters for me. Not much else to report, they come with a little clear plastic case for storing them and they work as expected.
UPDATE: After less than a year with two of these cards I've had to bin them both as they became unreliable. I shoot 360º panoramic images for Google and several images on a large shoot were corrupt. I initially blamed my 7D and noticed there was a firmware update for the 7D so did that but I'm not on a 2nd 7D and also notice corruption with my 5D3 and I've just had another batch of 300 images with one corrupt.
Unreliable cards may be OK for casual or holiday snaps but for business I should have known better than to buy based on price, both cards binned and Pro-grade cards purchased instead.
