Seagate Exos 7E8 ST8000NM001A 8TB SAS 12Gb/s 7200 RPM 256MB 3.5" internal hard drive

8 TB Enterprise SAS Hard Drive

The Seagate Exos 7E8 ST8000NM001A is a 3.5 inch internal hard drive built for enterprise storage workloads. It delivers 8 TB of capacity through a SAS 12Gb/s interface spinning at 7200 RPM with a 256 MB cache. Average latency is rated at 4.16 ms and the drive includes Protection Information (T10 DIF), SuperParity, Low Halogen construction, PowerChoice and PowerBalance technologies plus Advanced Write Caching backed by 2 M of internal NOR flash. A humidity sensor is also integrated.

Server and Array Builders Needing SAS 12Gb/s

This drive suits administrators deploying RAID arrays, backup appliances or high-capacity nearline tiers that require dual-port SAS connectivity and enterprise-grade firmware features. It is not for systems lacking a SAS host bus adapter or backplane, nor for platforms limited to 2.5 inch bays or interfaces other than SAS 12Gb/s. Buyers needing a different capacity point or a non-SAS interface should look at alternative models.

SAS 12Gb/s Interface Decides Compatibility

The single specification that determines fit is the SAS 12Gb/s interface; the drive must connect to a compatible SAS controller or expander to function. Without that link the 8 TB capacity, 7200 RPM spindle speed and 256 MB cache cannot be used. Verify the host system supports SAS 12Gb/s before purchase.
