300 GB 10K SAS enterprise drive

The Seagate ST300MM0048 is a 2.5-inch internal hard drive built for enterprise storage arrays. It spins at 10000 RPM and provides a 128 MB cache to handle write-intensive workloads. The SAS 12Gb/s interface connects directly to compatible controllers and backplanes.

SAS 12Gb/s interface requires matching host

This drive uses the SAS 12Gb/s standard, so the server or enclosure must support that signalling rate. Performance will fall back to the lowest common speed if the controller or expander only negotiates 6Gb/s or 3Gb/s. Cable length and backplane topology also affect realised throughput.

300 GB capacity sets the storage limit

The single drive offers 300 GB of usable space, which determines how many units are needed to reach a target volume size. Arrays requiring more capacity must add additional drives or select a larger model.

Perguntas sobre este artigo

Is the 300 GB capacity the only option in this Enterprise Performance 10K HDD series?

The supplier data lists only the 300 GB model for the ST300MM0048. Other capacities may exist in the same series but are not shown in the provided specifications.

What does the 10000 RPM speed deliver in a live server?

The 10000 RPM spindle reduces average latency and supports high transaction rates for write-intensive enterprise workloads.

How does the SAS 12Gb/s interface limit real-world throughput?

The SAS 12Gb/s link caps the maximum burst transfer rate at 12 Gb/s; sustained throughput will be lower and depends on the drive’s internal media speed.
