So I like the 5 year warranttee on the blacks, but it does look like the REDs are the way to go. And I think I'll also go with splitting my data between seagate and WD and possibly Hitachi (I know, they've been bought by WD) to make a three way RAID 1 mirror across 4Tb drives. Yes, I'd get more room out of RAID5, but I'm not that silly, and I don't need to move to 4 x 4Tb in RAID6 either. Who knows... still pricing things out.
