Seagate Savvio 15K.2 73GB SAS 6Gb/s Enterprise HDD

The Seagate Savvio 15K.2 ST973452SS is a 2.5 inch enterprise hard drive built for high-performance laptop and blade-server bays. It spins at 15000 RPM with a 16MB cache and connects through a SAS 6Gb/s interface. The bare-drive unit is sold new and carries the manufacturer's original 2016 introduction date.

Suits latency-sensitive workloads in compatible

This drive targets applications that benefit from low seek time and rotational latency in a small form factor. It is not for systems that lack a SAS controller, for users needing more than 73GB of capacity, or for buyers who require an active manufacturer warranty. The one-year coverage comes from the retailer, not the original maker.

15000 RPM spindle speed determines transaction rate

The 15000 RPM rotation delivers an average seek time of 2.9ms and average latency of 2ms, which are the primary drivers of random I/O performance. If the host chassis accepts a 14.80mm high 2.5 inch SAS drive, this spindle speed makes the model suitable for write-intensive enterprise workloads within its 73GB limit.

Questions about this item

Will the 2.5" 14.80mm height of the ST973452SS fit my laptop bay?

The drive measures 2.5" form factor with a maximum height of 14.80mm, width of 70.00mm and length of 100.50mm; verify your laptop accepts a 14.80mm tall 2.5" drive before purchase.

What is the correct way to connect the SAS 6Gb/s interface on the ST973452SS?

Attach the SAS data and power connectors firmly to the matching backplane or controller; the step often missed is securing the drive with screws so the high-vibration 15000 RPM spindle cannot loosen the connection.

When should I plan to replace the 73GB Savvio 15K.2 drive in a production server?

With a 15000 RPM spindle and 2ms average latency, treat the drive as a wear item; schedule replacement after the manufacturer end-of-sale date in 2016 or when SMART reallocated-sector counts begin to rise.
