Enterprise 2.5-Inch Nearline Drive

The Seagate ST2000NX0303 is a 2TB 2.5-inch hard drive spinning at 7200 RPM with a 128MB cache and SATA 6.0Gb/s interface. It is built for enterprise storage arrays and high-density data centres that need 24x7 environmental robustness in a 15mm z-height form factor.

Before ordering verify bay clearance

Confirm your chassis or server tray accepts a 15mm drive height and the 100.45mm length before ordering. The SATA 6.0Gb/s connection requires a compatible backplane or controller, and the 512E sector format must be supported by your RAID card or operating system for correct operation.

512E SED format and efficiency gains

The drive uses a 512E sector format with Self-Encrypting Drive technology to protect data at rest. Third-generation engineering delivers an 18% sequential performance improvement and over 50% improvement in watts per TB compared to the previous generation, lowering power costs for dense deployments.
