Enterprise 4 TB SAS Hard Drive

The Seagate Exos 7E8 ST4000NM004A is a 4 TB hard drive built for enterprise storage workloads. It uses a SAS 12Gb/s interface and spins at 7200 RPM with a 256 MB cache. The 3.5 inch form factor and 4Kn sector format suit rackmount NAS and server deployments that demand consistent performance.

Suited for high-capacity arrays.

This drive fits storage arrays, backup appliances and transactional databases that require sustained throughput and the dual-port resilience of SAS. It is not for systems that lack a SAS host bus adapter or backplane, nor for laptops or small-form-factor enclosures that only accept 2.5 inch drives.

SAS 12Gb/s interface dictates compatibility

The single specification that decides fitment is the SAS 12Gb/s interface; the host controller, backplane or RAID card must support this protocol to recognise and use the drive. Without a compatible SAS connection the drive cannot operate, regardless of capacity or spindle speed.

Questions sur cet article

How much heat does the ST4000NM004A produce when running all day?

The drive is built for enterprise workloads with a 7200 RPM spindle and SAS 12Gb/s interface, engineered to operate continuously in rackmount NAS environments.

What controller or backplane is needed to use this SAS 12Gb/s drive?

A SAS 12Gb/s host bus adapter or a compatible RAID controller with SAS ports is required; the 3.5 inch form factor fits standard enterprise drive bays.

Will the 4Kn sector format work with my older RAID card?

The drive uses 4Kn native sectors; the controller and operating system must support 4Kn addressing for the 4TB capacity to be recognised correctly.
