The flash controllers used on solid state disks implement wear leveling, to ensure hot blocks don't prematurely wear out on the flash device. Wear leveling will move hot logical blocks around in the physical flash memory, so one part doesn't wear out much faster than the rest of it. I would presume flash on USB sticks does something similar, but I don't know that for sure. -- Andrew _______________________________________________ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss
