BTW wrt speed.....if you are copying a lot of data locally (vs say SATA) then
it's a bit slower (not much) but once you then try shoving the data out over
the network (std ether-100) then obviously the ntwork becomes the limiting
factor.

wrt hotswapping etc I have both - a couple of nice quiet disks I use for stuff
like movies which I tend to leave on for long periods & others which I plug in
& switch on in order to do backups (using rsync).

& I'm playing with s/w raid on usb disks (on linux) esp mirroring as a
form of backup.

Course now you've mentioned all these windows nasties I'm sure the gremlins
will be waiting at my door.

Oh & & The nslu2 linux appliances I was playing with were all rock solid with
their USB2 storage.
