Enterprise 146 GB 15K SAS drive

The Seagate Savvio 15K.2 ST9146852SS is a 2.5-inch SAS hard drive spinning at 15000 RPM with 146 GB capacity and a 16 MB cache. It targets mainstream servers and storage arrays that need fast random access in a small form factor. The 6 Gbps SAS interface suits power-constrained and space-constrained data centres. A self-encrypting drive option adds hardware-based data security.

Sustained 15K RPM throughput

At 15000 RPM the drive maintains consistent rotational speed under continuous read and write workloads rather than throttling after short bursts. The 16 MB buffer absorbs command queues to keep the SAS link busy during heavy transaction processing. Sequential and random I/O patterns stay stable across extended operating periods. The SAS 6 Gbps link supports full-duplex traffic without the half-duplex limitations of older parallel interfaces.

Cool low-power operation

The manufacturer notes a low operating temperature that reduces power consumption and heat dissipation compared with higher-power 3.5-inch alternatives. This thermal profile enables quiet running in dense enclosures where airflow is limited. Lower heat output also eases cooling requirements for rack-mounted arrays. The 2.5-inch form factor contributes to the reduced thermal envelope.

Questions about this item

How much power and heat does the 15000RPM SAS drive generate during continuous operation?

The Seagate Savvio 15K.2 is designed for low operating temperature, so it consumes less power and dissipates less heat, ensuring cool and silent operation even under sustained workloads.

What host interface and controller does the ST9146852SS require to function?

This drive uses a 2.5-inch SAS interface running at 6Gbps, so it needs a compatible SAS controller or backplane that supports that link speed and form factor.

Will the 146GB 15K.2 work in a server that currently uses older 3.5-inch SAS drives?

Yes, the drive uses the same SAS protocol, but it has a 2.5-inch form factor, so the server must provide 2.5-inch bays or suitable adapters for physical installation.
