My previous blog about Memory Cards got me thinking, so here is more about Memory Cards:

Physically the largest memory card available is the CompactFlash Card. This format has been around since 1994, and is still popular in high end digital cameras. The largest capacity currently available is 32GB, with Samsung having announced a prototype of a 64GB CompactFlash card in 2006.

On the other end of the scale, the tiny, fingernail-sized microSD Card is physically the smallest. I always get a bit nervous when handling a microSD card as I’m concerned I may drop it and never find it again. Fortunately microSD cards are almost always packaged with SD Card adapters, so they can be read in SD Card readers. MicroSD cards are mainly used in cellphones, portable media players and handheld GPS devices. The largest capacity microSD (actually microSDHC – High Capacity) card currently available is 8GB.

Somewhere in between the microSD and the SD card format is the miniSD card format. It was originally intended for use in cell phones, digital cameras and MP3 players. It seems to be slowly being supplanted by the microSD card.

Some card manufacturers have a neat product which can be used as a microSD, miniSD or SD Card – like the SanDisk 2GB microSD Card with miniSD and SD Adapters.
