Best choice for RAID 1 mirror 2TB per drive?

i just got 2 x 2TB Samsung F4's for a RAID-1 mirror and i'm very impressed. the drives are really quiet compared to the 2TB Caviar Blacks in my Mac Pro, and they were a lot cheaper as well, half the cost.

also, i was specifically looking for 2TB 5400RPM vs. 7200RPM drives for the RAID-1 mirror because i wasn't looking for performance for a backup, just good quality and less noise. i jumped on a NewEgg deal a few weeks ago for the Samsung F4's, $79 each....i couldn't refuse at that price.
