The other hard drive. I'm currently putting together a new system, and
the storage is going to be 4 75GB ATA drives in a RAID 0+1
configuration. Even with my DLT4000 tape drive, backing up 150GB is just
not something I'm going to want to do very frequently, if ever. These
drives are cheap enough that it is feasible to use mirrored RAID
configurations, and have a spare drive on the shelf also. We're not
quite there yet, but we're close to the point where a second drive for a
mirror is cheaper than the media required to back up the drive to
something else. On second thought, if you include the cost of the tape
drive--even amortized over a number of tape sets--we passed that point a
while back.
