Unfortunately most embedded environments I've worked with, moving disks aren't really acceptable as the G forces will kill them... try saking your notebook around while it's runnning and slamming it against the wall, etc :-) Please don't call me for warranty <wink> I think it's extreemly important to focus on a GOOD flash file system---I'd settle for something a'la RT-11 and contiguous files---that doesn't have huge impact on flash re-write lifetimes. As for the IBM drives, they look mega-cool, and will probably be useful for a large number of applications, but I hazard they'll be IDE attached immediately, if not sooner, and therefore aren't anything to worry about :-) BTW, for those worrying about cramming it onto a 1.44Mb floppy for reasons of flash size, I went looking, and it's damned hard to find anything under 2MB of flash any more, and many many many boards support up to 72MB of FlashDisk. While I understand the need to conservce space---if not the need to spell correctly <wink>---I think that it is important to focus on what the embedded world needs, and make sure we can STRIP it to fit on a floppy, but not that we obsess over making sure it fits in all forms.
