DELL GM1R8 300GB 15000RPM SAS 12Gb/s 2.5" internal hard drive

300 GB 15 K SAS drive for Dell arrays

The Dell GM1R8 is a 300 GB 2.5-inch hard drive spinning at 15 000 RPM with a SAS 12 Gb/s interface. It ships new with a hot-plug tray designed for Dell EqualLogic PS4100 and PS6100 storage arrays. This drive targets administrators who need high-speed spindle storage inside those specific platforms. It is not suited for systems that lack a 12 Gb/s SAS backplane or the proprietary tray mounting.

Sustained throughput at 15 K spindle speed

At 15 000 RPM the drive delivers consistently low latency and high sustained transfer rates across the full SAS 12 Gb/s link. Sequential workloads such as database logs or streaming writes keep the media busy without the throughput collapse seen on slower spindles. Random I/O patterns also benefit from the short rotational latency inherent to the 15 K design. The drive cannot exceed the 12 Gb/s bus ceiling no matter the workload intensity.

Enterprise thermal profile and power draw

Built for continuous operation in dense 2.5-inch bays, the drive runs at typical enterprise temperatures when airflow meets Dell chassis specifications. Acoustic output is characteristic of a 15 K SAS spindle under load and is masked by array fan noise in normal rack deployments. Power consumption scales with the 12 Gb/s SAS activity and the 15 000 RPM motor current during steady-state operation.
