Enterprise nearline storage
The Seagate Constellation ES ST1000NM0021 is a 1TB 3.5-inch internal hard drive built for 24×7 operation in multi-drive servers and storage arrays. It spins at 7200 RPM with a 64MB cache and connects through a SAS 6Gb/s interface for enterprise workloads.
SAS installation and encryption
The bare drive fits standard 3.5-inch bays and connects with SAS data and power cables; no special mounting hardware is required. The Self-Encrypting Drive option uses 256-bit encryption, so the encryption key must be managed by the controller or host software to avoid data loss.
Suited for capacity-optimised servers
This drive suits administrators who need high-capacity, enterprise-class reliability with enhanced rotational vibration tolerance and an MTBF of 1.2 million hours. Buyers who want more storage per bay or require a SATA interface should consider other models.

คำถามเกี่ยวกับสินค้านี้
How can I verify the ST1000NM0021 is running correctly after installation?
Check SMART attributes for reallocated sectors and confirm the drive reports 7200 RPM, 64 MB cache and a SAS 6Gb/s link speed in your RAID controller or HBA utility.
What comes with the bare drive and what must I source separately?
The box contains only the 3.5-inch drive; you need a SAS 6Gb/s cable, compatible backplane or HBA, mounting screws and a power connector.
Which capacity of the Constellation ES line should I pick for a 24×7 server array?
This model provides 1 TB; choose higher-capacity Constellation ES drives if you need more space per bay.
