| Seagate ST91000642NS 1000GB 2.5″ 6.0 Gbps 7200 RPM Nearline Self Encrypting Drive Federal Information Processing Standards Constellation.2 Serial Advanced Technology Attachment Hard Disk Drive – Brand New
Constellation.2™ – Design Small and Deliver BIG—2.5-Inch, Eco-Friendly Nearline Drive
Key Advantages
- Second generation of the first 2.5-inch, mainstream capacity, 15mm z-height, nearline enterprise drive for space-constrained data centers.
- Choose SATA 6Gb/s for fast, economical Tier 2/nearline performance.
- The industry’s highest-reliability 7200-RPM drive, designed for 24×7 operation with MTBF of 1.4M hours and AFR of 0.62%.
- Enterprise-class firmware features and best-in-class rotational vibration tolerance maximize system availability and performance.
- Lowest operating power (under 6.4W) and enhanced PowerChoice™ options for additional power savings during slow or idle periods; Workload Management™ technology helps systems keep drives cool.
- Self-Encrypting Drive (SED) option (AES-256) cuts IT drive retirement costs while securely protecting data where it lives—on the drive.
- FIPS 140-2 Validated™ drives protect Sensitive but Unclassified and Protected class data.
