Compatibility
The ST2000NM000B uses a 3.5-inch SATA interface and native 512-byte sectors. Before installation, confirm that the server, controller, backplane, and operating system support the drive's interface, capacity, and physical dimensions. Although the drive is designed for enterprise use, compatibility with a particular RAID array or storage appliance should be checked with the system manufacturer.
Reliability and Data Integrity
Seagate specifies an MTBF of 2 million hours, an annualised failure rate of 0.44%, and a workload rating appropriate to its Exos 7E1 product class. Enterprise features include PowerChoice, PowerBalance, SuperParity, and advanced write caching. These manufacturer ratings are statistical specifications and do not guarantee the service life of an individual drive.
DC Supplies Product Note
Confirm the complete model number before ordering. The ST2000NM000B is the standard 2TB Exos 7E1 SATA model with 256MB cache and native 512-byte sectors. It is different from the ST2000NM006B self-encrypting drive variant. Verify the sector format and controller requirements when replacing an existing enterprise drive.
