Seagate Exos 7E10 4TB SAS enterprise drive
This Seagate Exos 7E10 ST4000NM001B is a 4TB 3.5-inch internal hard drive built for enterprise storage. It runs at 7200 RPM with a 256MB cache and connects through a SAS 12Gb/s interface. The drive is designed for 24x7 operation in mainstream data centre applications. Average latency is 4.16ms.
Suits hyperscale and RAID arrays.
This drive fits hyperscale cloud data centres, massive scale-out deployments, OLTP and HPC workloads, high-density RAID storage, mainstream enterprise external arrays, distributed file systems such as Hadoop and Ceph, enterprise backup and restore, and centralised surveillance. Buyers whose systems lack a SAS 12Gb/s host bus adapter or backplane cannot use this drive.
SAS 12Gb/s interface decides compatibility
The single specification that determines whether this is the right part is the SAS 12Gb/s interface. The drive requires a controller or backplane that supports SAS 12Gb/s signalling. Without that connection the drive will not function in the target system.

Questions about this item
Will the 3.5" 26.11mm high drive fit in a standard 3.5" bay?
Yes, the 26.11mm height matches the standard 3.5" form factor used in most server and storage chassis.
What is the correct way to connect the SAS 12Gb/s interface to avoid link errors?
Use a SAS 12Gb/s cable and backplane; the drive will negotiate down to 6Gb/s if the controller or expander only supports that speed.
How often should I check the 4TB enterprise drive for SMART reallocated sectors?
Monitor SMART attributes monthly; rising reallocated sector counts indicate media wear and the drive should be replaced before failure.
