Enterprise Capacity Fit

The Seagate Savvio 10K.3 ST9146803SS delivers 146GB of storage on a 2.5" SAS 6Gb/s interface spinning at 10000 RPM with 16MB cache. It is built for server and storage-array workloads where consistent throughput matters more than raw capacity.

Server Workload Suitability

This drive suits administrators who need a small, high-speed spindle for transaction logs, database indexes or tiered-cache layers in rack-mounted systems. It is not for buyers who want more storage per bay, nor for laptops or desktops that lack a SAS host adapter.

SAS 6Gb/s Interface Requirement

The drive connects exclusively through a SAS 6Gb/s port; a compatible controller or backplane is mandatory for operation. Verify that your chassis and HBA support this interface before purchase.

Questions about this item

Will the 16 MB cache or SAS 6Gb/s interface need firmware updates or component swaps later?

The drive ships with its factory firmware; no user-serviceable parts exist on the sealed 2.5" mechanism, so routine maintenance is not required.

Does the 10000 RPM spindle or 16 MB cache hit a throughput ceiling first during sustained transfers?

The 10000 RPM mechanical latency of 3 ms typically limits sustained random I/O before the 16 MB cache or SAS 6Gb/s link saturates.

How much heat and noise does the 10000 RPM 2.5" mechanism produce in all-day server use?

The 10000 RPM spindle generates audible seek noise and measurable heat; sufficient chassis airflow is needed for continuous operation.
