DELL 2M5JK 300GB 2.5" SAS 10K 12Gb/s internal hard drive

Dell 300 GB 2.5-inch SAS drive

This Dell 2M5JK is a 300 GB internal hard drive with a 2.5-inch form factor and a SAS 12Gb/s interface. It spins at 10,000 RPM and uses a 512n disk format. The bare drive is designed for Dell PowerEdge servers and the PowerVault MD3060e and MD3860f arrays. It suits administrators who need a direct replacement part for those specific platforms.

Sustained 10K RPM spindle speed

The 10,000 RPM spindle maintains consistent throughput during extended read and write workloads rather than relying on burst caching. A 12Gb/s SAS link keeps the bus saturated under heavy queue depths typical of database or virtualisation tasks. Mechanical latency remains stable because the rotational speed does not throttle under thermal load. This behaviour supports predictable I/O patterns in multi-tenant server environments.

300 GB capacity limit

The 300 GB capacity is the single specification that determines whether this drive fits the storage budget of the target array. Arrays that require larger volumes per spindle will need a different drive. The fixed capacity also fixes the cost-per-gigabyte calculation for capacity planning. Buyers who need more storage per bay cannot use this model.
