I'm currently running 5x 2Tb drives in RAID5, so I've got ~8Tb of space online.
2Tb is the sweet-spot right now, at about 90 bucks. In comparison, 3Tb drives
are around $250.
Personally, I don't like racks, enclosures or disk cards that do RAID independently. If the controller fails and you can't locate a compatible replacement, your data is stuck on the drives and you have no way of getting it
off. I use Linux's md driver. No (potentially) irreplacible hardware to fail.
