SanDisk Extreme Pro Compact Flash Memory card

Guest writing today we have film maker and Canon 5D Mark II owner, Alex Wolfe. Welcome Alex!


How does one explain a card like this? I know – above top of the line! Or <Greater than? I say this because SanDisk’s new Compact Flash(CF) card line, Extreme Pro, with it’s 16, 32, and 64 GB options, has more speed than we have need… for… sorry about the rhyme. I suppose I mean to say more speed than you could ever need, but of course that is not really true. The Sandisk Extreme Pro’s specs out perform most professional cameras including the Canon 5D Mark II. We’ll check out if all this speed is worth it, after the break.
By the way, here is a small refresher on the what and why of CF cards courtesy of Wikipedia:

CompactFlash (CF) is a mass storage device format used in portable electronic devices. For storage, CompactFlash typically uses flash memory in a standardized enclosure.

The format was first specified and produced by SanDisk in 1994. The physical format is now used for a variety of devices.

CompactFlash became a popular storage medium for digital cameras. In recent years it has been widely replaced by smaller cards on the consumer end, but it is still a preferred format for professional DSLR cameras, for its superior capacity and reliability.”

  1. There are some attention-grabbing cut-off dates in this article but I don’t know if I see all of them heart to heart. There is some validity but I’ll take hold opinion till I look into it further. Good article , thanks and we want more! Added to FeedBurner as well

  2. In the video, you say 90 MegaBITS per second, it should be 90 MegaBYTES per second.
