Enterprise storage drive

The Seagate Exos 7E8 ST4000NM003A is a 4TB 3.5 inch internal hard drive built for enterprise workloads. It spins at 7200 RPM and connects through a SAS 12Gbps interface with 256MB cache. The drive targets email, transaction processing, decision support, SAN and NAS deployments.

Not for desktop PCs without SAS

This drive suits servers and storage arrays that accept SAS 12Gbps drives and need 4TB of 7200 RPM capacity. It is not for systems that lack a SAS host bus adapter or RAID controller. It is also not for users who need a different capacity or a non-SAS interface.

SAS 12Gbps interface

The single specification that decides fit is the SAS 12Gbps interface. Your backplane, HBA or RAID controller must support this exact interface for the drive to function.
