Dell EMC 1TB 12Gb/s SAS drive

The Dell EMC ST1000NX0473 is a 1TB internal hard drive with a 12Gb/s SAS interface. It operates at 7200rpm and provides a 128MB buffer. The 512e format and 2.5-inch form factor suit server and storage array installations.

Suited for 12Gb/s SAS bays.

This drive fits servers and arrays that support a 12Gb/s SAS connection. Buyers whose hardware only offers other interface types should look at something else. The 1TB capacity addresses moderate nearline storage requirements.

12Gb/s SAS interface decides compatibility

The single specification that determines fit is the 12Gb/s SAS interface. A compatible backplane or controller is mandatory for operation. The 7200rpm spindle speed and 128MB cache then define the sustained throughput level.

Questions about this item

How do I install this 1TB SAS drive in a server, and what step is often missed?

Mount the 0.6-inch high drive in a 3.5-inch bay, connect the SAS data and power cables, then configure the 512e disk format in the RAID controller before initialising the volume.

What maintenance or replacement will this ST1000NX0473 drive need over time?

The 7200rpm mechanical mechanism and 128MB buffer have no user-serviceable parts; plan to replace the unit once SMART attributes indicate wear or after the rated workload limit is reached.

Which limit appears first when this drive runs sustained workloads?

The 12Gb/s SAS interface bandwidth and 7200rpm spindle speed together cap sustained transfer rates, so the interface throughput ceiling is reached before thermal limits.
