Enterprise 1TB SAS drive

The Seagate ST1000NX0333 is a 2.5-inch enterprise hard drive with a 12Gb/s SAS interface, 1TB capacity and 128MB cache. It spins at 7200 RPM with an average latency of 4.16ms and fits a 15mm z-height for high-density server and storage arrays.

Who it suits and who it does not

This drive suits administrators deploying nearline storage in 2.5-inch bays that accept a 15mm height and provide a SAS 12Gb/s host connection. It is not for systems that only accommodate thinner drives, nor for hosts lacking a SAS controller or backplane.

Deciding specification

The SAS 12Gb/s interface is the single specification that determines whether this drive can be installed; the host must support 12Gb/s SAS signalling for the drive to function.

Kysymyksiä tästä tuotteesta

How do I install the 2.5-inch 15mm SAS drive in a laptop bay, and what step is often missed?

Mount the drive using the 70.10mm by 100.46mm screw pattern, connect the SAS 12Gb/s data and power cables, then ensure the backplane or HBA is configured for 12Gb/s link speed — many builders leave it at 6Gb/s by default.

What maintenance or replacement will the 7200 RPM nearline drive need during its service life?

The drive is sealed with no user-serviceable parts; plan to replace the unit once its rated workload or error-rate thresholds are reached, and keep firmware current via the SAS interface to maintain 24x7 reliability.

What limit appears first when the 1TB drive runs sustained writes at 7200 RPM?

The 128MB cache absorbs bursts, but continuous streaming hits the mechanical throughput ceiling of the 7200 RPM platters before the SAS 12Gb/s bus saturates, so sustained throughput settles at the media rate.
