Although I’ve been very happy with the performance of the PRETEC SDXC 64GB cards I’ve been using, the toughness of a CF card still wins compared to the thinner lighter weight SD cards. Plus the combination of a 32GB CF card and a 64GB SDXC card in the camera gives me close to 90GB of footage before I have to change anything out. This basically means a whole day worth of shooting in many cases.

You still pay a premium for larger capacity compact flash cards. These Transcend 32GB CF cards are about $63 a peace, which is down from last years pricing but still about twice the dollar to GB ratio of the 64GB SDXC cards I’ve been using. I haven’t had a chance to do any speed tests yet, but it shouldn’t be hard for most cards to keep up with the 11MByte data rate of the new ALL-I format of the 5d mark III.

Once I’ve had a chance to do some speed tests on these Transcend 32GB CF cards, I’ll post some results on how they stack up against the very fast SDXC cards I’ve been using. More info to follow.
