Ok, I stand corrected, to a degree - according to Wikipedia apparently SD cards do have wear leveling (dynamic, shorter life expectancy, but still better than none whatsoever) whereas SSDs do have wear leveling (static, longer life expectancy).
So while SSDs actually do the active tracking and remapping and wear leveling around kind of thing, SD cards apparently have an "empty sector pool" where they grab sectors out of.
I also found a document by Sandisk
http://www.scribd.com/doc/7010332/SA...-Wear-Leveling where they write that this type of wear leveling works fine for large continuous writes but not all that well for small changes. But then again this document is from 2003 so who knows if it still applies.
Even so - any human made storage media fails sooner or later - the SD card is easy to replace, the internal memory is not, so I try to use the SD card.
