The new Cheetah 15K.7 drives will ship in 300GB, 450GB and 600GB versions, with 4Gbps Fiber Channel or 6Gbps SAS 2.0 interfaces. Drive-based encryption is also available as an option. All of the drives come with 16MB of DRAM cache, have an expected MTBF of 1.6 million hours and are backed by a five-year warranty. They’ve also been designed to be as power efficient as possible using Seagate's Powertrim technology, which dynamically optimizes power consumption without affecting speed.
Performance-wise, Seagate’s latest drives still lag behind high-end SSDs but may prove a great alternative for capacity hungry environments.
