So, if you were looking for reliable 2TB HDD (to be used in RAID 1 for a home server, and possibly stay up and running for years until they become too small), what would you guys recommend? Most likely recommendations on this thread are perfectly good when looking for reliability, but I've been looking in particular to these ones:

Western Digital Caviar RE4 2TB 64MB SATA-II
Western Digital Caviar RE4-GP 2TB 64MB SATA-II
Western Digital Caviar Black 2TB 64MB SATA

I'll be happy with performances, but that would have no priority over reliability and long MTBF. I am looking for the differences in tech spec, but maybe somebody here already knows? I ranked them by decreasing price on my usual shop.

For years I've purchased IBM/Hitachi HDD, but can't easily find any. Also, I recently had really bad experiences with Seagate, and I'd rather stay away from those in this particular instance. So, it really seems to me that WD is the only alternative left.
