Key Features
Superior reliability - Designed and manufactured to server-class standards to provide best-in-class enterprise reliability in high duty cycle environments. With 1.2 million hours MTBF, these drives have the highest available reliability rating on a high-capacity drive.

High capacity - Up to 750 GB of storage packed with server-class features and low cost-per-gigabyte value.
