Which 2TB-3TB drives would be good for RAID 1 (mirroring)?

When I build my next system I am thinking of putting 2 large drives in Raid 1 for data protection and I'd like to know which drives would work for this purpose?

Thanks,
BGC
 
These drives seem very expensive compared to other 2-3TB drives. Why is that? Reliability? I'm thinking of doing the same thing as the OP. Anything wrong with 5400 RPM drives?
 
out of the "green" drives, the WD20EARX (2TB caviar green, SATA III version), WD 2TB RE4GP (enterprise version of the caviar green), and seagate barracuda green 2TB are generally suitable for RAID1. none of these drives spin down after a few seconds of inactivity.

and yeah, the drives Blain posted tends to be faster and more reliable than most other drives, though i'd probably use the WD black and 7200RPM RE4 in RAID0 or RAID4/5/6/10 instead. these are performance drives, after all.
 
I don't mean to hijack your thread OP, but I'm in the same scenario. I was hoping to spend less than $200 for both disks. Is there any benefit to the newer disks with less platters for this purpose?
