Enterprise 4 TB SAS drive

The Seagate Exos 7E10 ST4000NM025B is a 3.5-inch enterprise hard drive built for 247 bulk-data workloads. It delivers 4 TB of capacity over a SAS 12Gb/s interface, spins at 7200 RPM and provides a 256 MB cache. The drive carries a 2 million hour MTBF rating and supports 550 TB per year of writes.

NAS and server builders

This drive suits administrators deploying high-capacity storage in NAS arrays or enterprise servers that require SAS connectivity and sustained throughput. It is not for desktop PCs or laptops that lack a SAS backplane or compatible host-bus adapter, nor for workloads that demand solid-state latency.

12 Gb/s SAS interface

The single specification that decides fit is the SAS 12Gb/s interface. Only systems with a SAS controller or backplane operating at 12 Gb/s can attach and run the drive at its rated speed.
