SD cards tend to be much cheaper than CF cards, but CF cards tend to be faster and more durable than the smaller fragile SD cards. SD cards are easier to misplace or damage, but if you keep your memory cards in a memory card wallet (as you should) it shouldn't be an issue.

7/30 · Hi, a) The only difference between CFExpress and SD is speed. Unfortunately it's almost impossible to know how fast a CFExpress card is -- the numbers printed on cards are garbage. SD cards have speed ratings, which go up to v90, which is 90 MB/s -- i.e. 720 Mb/s. (Note that B is bytes, b is bits.)

Compact Flash card write speeds top out at around 160 or so MB/s, and SD cards will max out at about 250MB/s, with most being slower. XQD cards are already offering write speeds of 400MB/s and higher, with an upper limit that isn't actually known yet for sure, but definitely in the over 1GB/s range - maybe over 2GB/s or higher.

With its 38.5 (W) x 29.8 (L) x 3.8mm (H) dimensions, it is physically smaller than CompactFlash / CFast cards and it has

Technical Specifications of CF Cards. The size and speed of a CF card are usually mentioned on the front label. This type of card is available in a variety of sizes from 4GB to 512GB. There are two types of Compact Flash cards- “Type I” and “Type II.”. The physical size of Type I cards is 3.3 mm thick, while the thickness of Type II is

SD cards are more durable than you give them credit for. Try snap one some time! Also, scratches on the contacts are only cosmetic, and CF cards aren't just

7/16 · It’s been two years since I wrote this article and I thought I’d revisit my opinion/knowledge of the CF vs. SD card debate. I still think CF cards are a waste of money. I shoot professionally with many cameras, the Nikon D810 being one of them, and I rarely use the CF slot (if I do it’s purely to back up the SD card but it seems redundant to me).
