Enterprise server storage

The Seagate Savvio 15K.3 ST9146853SS is a 146GB 2.5" internal hard drive built for enterprise servers. It spins at 15000 RPM with a 64MB cache and connects via a SAS 6Gb/s interface. The drive meets regulatory data security compliance requirements and is FIPS 140-2 validated for sensitive data protection.

Server administrators needing validated security

This drive suits server environments requiring high-speed SAS storage with hardware-level encryption validation. Buyers needing larger capacities, desktop compatibility, or drives without FIPS 140-2 validation should look elsewhere as this unit is designed specifically for compliant enterprise server deployments.

SAS 6Gb/s interface requirement

The SAS 6Gb/s interface is the single specification that determines compatibility; this drive will not function on systems lacking a SAS controller or backplane. The 15mm height and 146GB capacity are fixed attributes that must match the server bay and storage allocation plan.

Questions about this item

Should I choose the 146GB or 147GB capacity version of the Savvio 15K.3?

The drive is supplied as 146GB; the 147GB figure appears in a used-listing description and represents the same physical capacity.

What does the 15000 RPM spindle speed mean for real-world server workloads?

15000 RPM yields 2 ms average latency, giving up to 21% better sequential read and write throughput than slower enterprise drives.

How does the SAS 6Gb/s interface limit performance in practice?

The SAS 6Gb/s link caps the external transfer rate at 6 Gb/s, so sustained throughput cannot exceed that bus ceiling.
