Hmm, I don't have 10Gb worth of disks at home ;-) Tapes are a bit of an issue, in supporting customers I learned you can screw the tapes. Never succeeded in botching one myself but as we all know customers tend to be better at breaking things. > > /usr Solaris filesystem.

Come on, they are 'Born to Stream' ;-) The Sun could do it, so I don't see why a decent FreeBSD system could not do it. FWIW the single disk I pulled data from on the Sun is an identical model to the one in my Asus @ home. A controllerbased raidarray on the Sun proved to be better in getting the drive to stream but it is not impossible to do it from a single disk.
