2 TB SAS enterprise drive
The Seagate Exos 7E8 ST2000NM004A is a 3.5-inch internal hard drive built for enterprise storage systems. It delivers 2 TB of capacity on a SAS 12Gb/s interface with a 7200 RPM spindle and 256 MB cache. The drive uses conventional magnetic recording technology rated for 24×7 operation in data centre environments.
Suited for bulk data arrays; not for desktop boot
This drive fits RAID and replicated multi-drive deployments that demand sustained write throughput and rotational vibration tolerance. It is not intended for single-drive desktop boot use, nor for workloads that exceed the 550 TB per year rating. Buyers needing higher single-drive capacity should consider larger models in the same series.
2 TB capacity with 550 TB annual workload
The 2 TB volume handles bulk archives, backups and unstructured data sets in always-on arrays. Headroom is defined by the 550 TB yearly workload limit and 2 million hour MTBF rating. Beyond that threshold, sustained heavy write patterns will exceed the design envelope and require additional drives.

Auf LagerFragen zu diesem Artikel
Will my server backplane need a SAS 12Gb/s controller for this 2TB drive to operate?
Yes, the drive uses a SAS 12Gb/s interface, so the host controller or backplane must support that speed for full operation.
Does the 256MB cache and 4.16ms latency help maintain steady throughput when paired with earlier 7200 RPM drives in a RAID set?
The 256MB cache and 4.16ms average latency are designed for consistent performance in multi-drive RAID environments alongside similar enterprise drives.
How can I confirm the drive is running at 7200 RPM with the full 256MB cache after installation?
Check the SMART data or controller BIOS for the reported rotational speed of 7200 RPM and cache size of 256MB to verify correct operation.
