Enterprise server storage

The Seagate Savvio 10K.4 ST9450404SS is a 450GB 2.5 inch enterprise hard drive spinning at 10000 RPM. It uses a SAS 6Gb/s interface and is designed for server workloads that demand consistent throughput and low latency. The drive carries a 2 million hour MTBF rating and a 0.44 percent annualised failure rate. It suits IT teams building or repairing high-duty storage arrays.

Compatibility checks

Verify that your server or storage chassis accepts 2.5 inch SAS drives and that the backplane or controller supports 6Gb/s SAS signalling. The drive is supplied as a bare unit without a mounting tray or caddy. Confirm the system firmware recognises the ST9450404SS model before deployment. Ensure adequate airflow in the drive bay for sustained operation.

Thermals noise and power

The 10000 RPM spindle speed produces measurable vibration and audible seek noise typical of enterprise SAS drives. Average seek time is 4.08ms and average write time is 4.65ms with 3ms average latency. SFF design and low power consumption reduce cooling and energy costs in dense racks. Expect higher thermal output than slower nearline drives under continuous load.

Questions about this item

Does the bare drive include a mounting tray or caddy for a 2.5" SAS bay?

The drive is supplied as a bare unit without a tray or caddy; you will need to obtain a compatible 2.5" SAS carrier separately.

Is the 450 GB capacity the only option in the Savvio 10K.4 line or are larger sizes available?

This specific model ST9450404SS is the 450 GB variant; other capacities in the same series would carry different part numbers.

How does the 10000 RPM spindle speed affect latency and seek performance in a server workload?

The 10000 RPM rotation yields a 3 ms average latency, 4.08 ms average seek time and 4.65 ms average write time for fast transactional I/O.
