Enterprise server storage

The Dell ST300MM0008 is a 300GB 2.5 inch internal hard drive built for enterprise servers and storage arrays. It suits administrators who need reliable capacity for transactional workloads or database logging. The drive delivers 10000RPM rotational speed and a 12Gb/s SAS interface for consistent throughput.

SAS host and caddy requirements

Installation requires a server or controller with a 12Gb/s SAS backplane and an available 2.5 inch drive bay. The included R Series caddy secures the drive in Dell PowerEdge R series chassis without extra brackets. A 128MB buffer helps sustain random I/O during mixed read and write operations.

Zero-hours assurance and bundled caddy

The unit ships with zero accumulated power-on hours, confirming a fresh deployment state. The supplied R Series caddy eliminates the need to source a compatible tray separately. This combination reduces setup time for replacement or capacity expansion projects.

Questions about this item

At what rotational speed does the 300 GB drive hit its thermal limit during sustained writes?

The 10000 RPM spindle speed is the primary factor that determines thermal behaviour under continuous load.

How much noise and heat does the 2.5 inch SAS 12Gb/s drive produce when running all day?

The 10000 RPM mechanism generates typical enterprise-level acoustics and heat; the included R Series caddy aids airflow in a server chassis.

Which controller or backplane must I already have for the ST300MM0008 to function?

A SAS 12Gb/s host bus adapter or RAID controller with a 2.5 inch drive bay is required for the 12 Gb/s interface.
