Cost effective enterprise-class storage
Get the right blend of performance, reliability and capacity and keep your total cost of ownership low.

24x7x365 reliability
Choose the storage foundation specifically designed for SMB to high-end NAS and large-scale datacenter replication environments running 24x7x365.

Designed for quality and reliability
Datacenter drives undergo at least 5 million hours of functional testing, and over 20 million hours of comprehensive Interoperability testing in an extensive array of server and storage systems. Please see the product AVL list for more info.

Dual processor
Twice the processing power to maximize performance.

RAFF rotational vibration cancellation technology
Enhanced Rotary Acceleration Feed Forward (RAFF) technology includes sophisticated electronics to monitor the drive and correct both linear and rotational vibration in real time. The result is a significant performance improvement in high vibration environments over the previous generation of drives.

Dual actuator technology
A head positioning system with two actuators that improves positional accuracy over the data track(s). The primary actuator provides coarse displacement using conventional electromagnetic actuator principles. The secondary actuator uses piezoelectric motion to fine tune the head positioning to a higher degree of accuracy.

Multi-axis shock sensor
Automatically detects the subtlest shock events and compensates to protect the data.

RAID-specific, time-limited error recovery (TLER)
Prevents drive fallout caused by the extended hard drive error-recovery processes common to desktop drives.
