A 4 TB, 7200 RPM SAS hard drive with a 12 Gbps interface and 128 MB cache for 3.5-inch bays

  • 4 TB capacity for large data sets
  • 7200 RPM spindle speed for quick access
  • SAS 12 Gbps interface for high throughput
  • 128 MB cache to smooth burst workloads
  • 512 n sector format for broad compatibility

4 TB SAS enterprise drive

The Seagate EXOS 7E8 ST4000NM0025 is a 3.5 inch internal hard drive with a 4 TB capacity. It spins at 7200 RPM and connects through a 12 Gbps SAS interface. A 128 MB buffer supports sustained data transfers. The unit is supplied in new condition.

Suited for SAS bays; not for hosts lacking SAS

This drive fits servers and storage arrays that provide native SAS connectivity. It is not suitable for systems that only offer other interface types. Buyers needing a different interface should look at alternative models.

12 Gbps SAS interface decides fit

The single specification that determines compatibility is the 12 Gbps SAS interface. The host backplane or controller must support this exact standard for the drive to function. Verify the interface before purchase.

Perguntas sobre este artigo

Will the 12 Gbps SAS link stay saturated under continuous 7 200 RPM workloads?

The drive runs at 7 200 RPM with a 12 Gbps SAS interface and 128 MB cache to sustain throughput during extended use.

How much heat and noise does a 3.5 inch 7 200 RPM SAS drive add to a server running all day?

At 2.0 pounds the 3.5 inch mechanism produces typical enterprise-level acoustics and thermal output for continuous operation.

Which SAS controller or backplane do I need to connect this 12 Gbps drive?

Any 12 Gbps SAS HBA, RAID card or backplane with a standard 3.5 inch SAS connector will support the ST4000NM0025.
