Seagate ST9500621SS 500GB 2.5" 6.0 Gbps 7200 RPM Nearline Self-Encrypting Drive Constellation.2 Serial Attached SCSI Hard Disk Drive – Brand New
Constellation.2™ - Design Small and Deliver BIG—2.5-Inch, Eco-Friendly Nearline Drive
- Second generation of the first 2.5-inch, mainstream capacity, 15mm z-height, nearline enterprise drive for space-constrained data centers.
- Choose 6Gb/s SAS for data integrity, scalability and fast data access.
- 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.
This drive is compatible with any server that accepts 2.5"x15mm (SFF Hard Drive) SAS Drives.
