Always wondered about these little waterproof cases for SD cards but never actually though about how waterproof SD cards are.
So I've looked it up.

Seems that SanDisk SD, SDHC, microSD and microSDHC memory cards are tested to withstand up to 72 hours in 1m salt or fresh water; IEC 529 IPX7
If you're wondering what the IPX thing is about
http://en.wikipedia.org/wiki/IP_Code
So 72 hours in 1 meter of salt water. Hmm might as well keep them in your pocket.
