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.

이 상품에 대한 질문

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.
