Data Sheet ™ 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 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 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 1 costs while securely protecting data where it lives—on the drive. ™ • FIPS 140-2 Validated drives protect Sensitive but Unclassified and 1,2 Protected class data. Best-Fit Applications • Storage-hungry business applications • Storage area networks (SAN) and network attached storage (NAS) • Maximum-capacity servers and blade servers • Rich media content storage • Enterprise backup and restore—D2D, virtual tape • Cloud computing 1 Self-Encrypting Drives (SED) and FIPS 140-2 Validated drives are not available in all models or countries. May require TCG-compliant host or controller support. 2 See FIPS 140-2 Level 2 Certificate at http://csrc.nist.gov/groups/STM/cmvp/ documents/140-1/1401val2011.htm#1635 ™ Constellation.2 Design Small and Deliver BIG—2.5-Inch, Eco-Friendly Nearline Drive 6Gb/s SAS SATA 6Gb/s Specifications 1 1 1 1 1 1TB 500GB 1TB 500GB 250GB Standard Model Number ST91000640SS ST9500620SS ST91000640NS ST9500620NS ST9250610NS 2 2 2 2 2 SED Model Number ST91000641SS ST9500621SS ST91000641NS ST9500621NS ST9250611NS 2,3 2,3 2,3 2,3 2,3 SED (AES-256) FIPS 140-2 Model Number ST91000642SS ST9500622SS ST91000642NS ST9500622NS ST9250612NS Features Protection Information Yes Yes — — — Low Halogen Yes Yes Yes Yes Yes Reliability/Data Integrity Mean Time Between Failures (MTBF, hours) 1.4 million 1.4 million 1.4 million 1.4 million 1.4 million Reliability Rating @ Full 24x7 Operation (AFR) 0.62% 0.62% 0.62% 0.62% 0.62% Nonrecoverable Read Errors per Bits Read 1 sector per 10E15 1 sector per 10E15 1 sector per 10E15 1 sector per 10E15 1 sector per 10E15 Power-On Hours per Year 8760 8760 8760 8760 8760 Bytes per Sector 512, 520, 528 512, 520, 528 512 512 512 4 Limited Warranty (years) 3 3 3 3 3 Performance Spindle Speed (RPM) 7200 7200 7200 7200 7200 Cache, Multisegmented (MB) 64 64 64 64 64 Interface Access Speed (Gb/s) 6.0, 3.0, 1.5 6.0, 3.0, 1.5 6.0, 3.0, 1.5 6.0, 3.0, 1.5 6.0, 3.0, 1.5 Max.
