sync supposed effect to kill flash media is a myth which has been dismantled on linux kernel mailing list recently :) The big problem people are seeing at the moment with latest linux kernel is that "sync" has been correctly implemented in vfat (which is probably most used FS for usb removable media), causing extremely slow operations for any write attempt. Before that, sync was not working properly but nobody really noticed. This is why this option was disabled in HAL cvs and in most distributions, until a new option is implemented in Linux kernel to flush caches really fast.
