- Second generation of the first 2.5 inch, mainstream capacity, 15mm
z-height, nearline drive for space-constrained data centres
- Choose 6Gb/s SAS for data integrity, scalability and fast data access,
or SATA 6Gb/s for fast, economical Tier-2/nearline performance
- The industry’s most reliable 7,200 RPM drive, designed for 24×7
operation with an MTBF of 1.4M hours and an AFR of 0.62%
- Enterprise-class firmware and best-in-class rotational vibration
tolerance maximise system availability and performance
- Lowest operating power (under 6.4W) and enhanced PowerChoice™
options for additional power savings during slow or idling periods;
Workload Management™ technology helps systems to keep drives cool
- Self-Encrypting Drive (SED) option (AES-256) cuts IT drive retirement
costs while protecting data securely where it lives — on the drive1
- FIPS 140-2 Validated™ drives protect data classed as Sensitive but
