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.

Vragen over dit artikel
How often does the 2M internal NOR flash used for Advanced Write Caching need replacement?
The 2M internal NOR flash is a permanent component sealed inside the drive and is not designed for user replacement.
Which limit appears first when the ST8000NM001A runs sustained workloads at 7200 RPM?
The SAS 12Gb/s interface bandwidth and the 4.16ms average latency set the performance ceiling under continuous operation.
How much heat and noise does the 8TB Exos 7E8 produce during all-day operation?
PowerChoice and PowerBalance technologies manage power draw to reduce heat and acoustic output during extended use.
