Seagate Savvio 15K RPM enterprise drive

The Seagate Savvio ST973451SS is a 2.5-inch internal hard drive built for enterprise notebooks and blade servers that require a SAS 3Gb/s connection. It spins at 15000 RPM with a 16MB cache to deliver low-latency access for transaction-heavy workloads. The unit is supplied new in retail or OEM packaging.

Fits SAS 3Gb/s bays; not for other interfaces

This drive suits systems that accept a 2.5-inch SAS 3Gb/s device and benefit from the 15K spindle speed. Buyers whose hardware only supports a different interface cannot use this drive. The manufacturer has ended sales and no longer provides a warranty on this model.

SAS 3Gb/s interface decides compatibility

The single specification that determines fit is the SAS 3Gb/s interface; the host must provide that exact connection. No other interface is supported by this model. Verify the system drive bay and controller before purchase.

Questions about this item

Does my system need a SAS 3Gb/s controller for the Savvio ST973451SS to function?

Yes, the drive uses a SAS 3Gb/s interface and requires a compatible SAS controller or HBA with a matching 2.5-inch drive bay.

Can the 2.5-inch Savvio ST973451SS share a SAS backplane with older 3Gb/s drives?

The 2.5-inch form factor fits the same physical bay, and the SAS 3Gb/s link will operate at the speed of the slowest device on the channel.

How can I verify the ST973451SS is running at its rated 15000 RPM after installation?

Check the drive’s reported rotational speed in your RAID controller BIOS or SMART monitoring tool; it should show 15000 RPM for this Savvio model.
