  For what it is worth I prefer the Raid 10. It provides less capacity than
  the Raid 5 but the Write performance is so much faster. I use the Raid 10
  as my main library and then incremental backups to other SATA drives. I
  also copy data to other drives for off site backup.

  Just a tad more info for Raid.. For most folk here I would think that
  mirroring between two drives side isthe way to go.. It is the slowest
  preformer both reading and writing.. but it is redundant.. If yo udo it in a
  hardwar e2 drive set up an dhav ea couple extra trays with drives you can
  create an off site back up on teh week end and keep it some where else.. As
  a note it's not the greatest way to go however to select huge drives for a
  raid set up if you can manage a few more smaller drives to fill the gaps
  your better off.
  Their are many different Raid specks and probably the most popular on a home
  or small business level is Raid 5 if you nee dmore room and a bit of
  preformance. It would use 4 drives that would be striped and with parity..
  So you can loose one drive and still retain all your data .. So typically
  you want a spare on hand.. This is quite reliable and also very
  fast..Remember that the systems today can read multiple drives at one time
  so it significantly faster then a mirror set up which just reads one..

  Doh. Of course I meant *RAID 1* mirror. It's an off-by-one error :-)
  (I knew what I *meant* to say)

  Mike is completely correct - RAID 0 "striping" is done to increase
  performance at the expense of reduced overall reliability.

  RAID 1 substantially improves reliability at little or no cost to
  performance (actually, read performance can be substantially
  better, write performance slightly worse).

  Personally, I strongly recommend running a RAID 1 pair as the
  "system drive" in general.
