the best combination of superior reliability, high capacity, and optimum

performance for enterprise applications.

Product Benefits

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.
