If you are a little more technically inclined I use a SANS Digital enclosure.

eSATA, although I paid like 160 just a couple of months ago.
I run it as 4 independent drives.

Not a huge believer in consumer level RAID, I have heard good things about DROBO though.

I did pay less, this one is eSATA only
