We install high-end surveillance DVRs, some using four- and eight-drive RAID5 arrays, all of which can REALLY put a strain on drives, with sustained 24/7 read/write access. We've seen a lot of different drives come and go (including a ton of those Maxtor thin drives blowing up). Currently we're using the 1TB and 2TB WD Blacks and been very happy with them. One site, we've had four of eight Seagate 1TB Barracudas in an array fail (all within barely two years of service, the first within a few months), and replaced them all with the Blacks.
