Hitachi's Ultrastar C10K600, Seagate's Constellation.2, and Seagate's Savvio 10K.5 are examined and compared in this article on Toms Hardware. All three support the established interfaces and configuration paths with SAS 6 Gb/s ports, and some models even come with Fibre Channel support. The test candidates prove to be reliable: Hitachi and Seagate estimate the MTBF for their C10K600 and Savvio 10K.5 at around 2 million hours, which is a high standard even in the enterprise segment.
