Hard drives are a really shitty solution.
They have something like a 40% failure rate, and they really are slow.. Even the fastest scsi drive is slower than tape because of the way the media is.
Tape is a STREAMING media.. So for backups and restores, it's very, very efficient. You just dump the data and it writes block 1, block 2, block 3.
Hard drives write in this fucked up cylinder/sector situation, and NOT sequentially either. Anybody who's telling you that hard drives are faster and more reliable and cheaper (in the long run) than tape is a rank amateur.
