Bought an refurbished 7D again, the 60D has an sensor damage. 1000X is currently the CF fastest card. The 7D will work with UDMA 7.
What is the maximal -senseful- CF card speed I can use on the 7D?
My old CF card (233x) might be topped.
Tell me your experience and your used product. I wan to buy 2 16GB cards.
1066x is the current fastest card (from Toshiba)... but alas since it's new it's way overpriced.
Another thing that ML and EOSHD has taught us is that even you though you buy into a "1000x" speed card, there's a HUGE difference in actual read / write speed.
Several tests including Sandisk and Lexar have by now shown that the fastest 1000x cards are the 64gb Komputerbay CF cards.
For some reason read and write speeds seem to drop on both the 32gb and the 128gb. Usually flash memory gets faster the more there is. Apparently that was a myth.
So there you have it.
Another bonus: Komputerbay cards are cheaper than both Lexar and Sandisk.
I just bought one card which does Canon 5D mk III raw without a hitch, and have another card coming this money. Best money spent.
