"Seagate has sent us its second generation Constellation.2 1TB drive (ST91000640NS). Aimed at server and database centers such as HP and Google, the Constellation.2 is designed with reliability in mind. While the drive's performance is important and its 1TB storage capacity is impressive, the drive's reliability is the most essential factor for servers and database centers. The drive has 1.4 million hours of Mean Time Between Failure Rates (MTBF), which roughly translates to 150 years. Furthermore, Seagate has recently introduced a new system for rating the drive's reliability--Annual Failure Rate (AFR). The AFR is Seagate's estimation of the percentage of products that will fail in one year."
