A lot. Don't believe anyone who tells you otherwise. (That doesn't
mean you can't learn this stuff as you go along; just be prepared
to learn a lot.)

Yes they do. I recently moved moved our NFS/SMB-shared directories
from internal (SCSI) hard drives to a RAID box. CPU I/O wait time
went from 16% down to 4% (that's on a 2-CPU 2Gb RAM UltraSPARC).
Of course if your fileserver doesn't do anything except serving
files, you can live with high wio time... YMMV.

...Then with
> mirror disks do you really need a tape backup?

You always need backup. At least two.
