I'm working on a review of memory cards for issue 30 of Advanced Photographer magazine. Actually, I have so many cards (22 CF and 36 SD) that the test might have to stretch over two issues.
So far, I reckon I have spent five days on it, including getting the kit in, photographing the cards and then doing the various tests using a Nikon D800 and Canon EOS-1 D X/EOS 6D DSLRs. I used a benchcheck software too.
The test process I will outline in more detail once the review has gone live in the magazine - the issue is due out mid-April - and I will add the review to this website too. I have to say I found the whole process very interesting despite the huge amount of time and effort it has taken.
