Note that a common 256 MByte flash card, in binary format, can hold over 9 years of data that is logged at 256 bytes every 5 minutes.

Actually, I belive Artos said he wants to log 256 bytes every 5 *seconds*, not every 5 minutes. If he's logging 256 bytes every 5 seconds then 256MB flash would last about 2 months.
