Most (all?) of the standard Flash memory devices these days have onboard controllers which can detect failing sectors in the flash memory, and will reroute data to spare sectors, much as HDs do these days.
Are you sure? The JFFS2 folks don't seem to think so and anecdotal evidence seems to bear me out.
Compact Flash has onboard smarts to do wear-levelling, etc, and presents an IDE-compatible interface. JFFS2 is meant for vanilla flash, where you're getting directly at the stuff and have to implement all of that yourself. I can't speak for the other flavours of consumer-grade removable flash, but they'd be somewhere on the spectrum between those two. Leaving off the smarts will of course give you a smaller and cheaper device. -- Anthony de Boer -- The Toronto Linux Users Group.
