DELL ST1200MM0007 1.2TB SAS 10K 2.5" internal hard drive

Dell 1.2TB SAS 10K 2.5" drive

This 1.2TB SAS hard drive spins at 10K RPM in a 2.5-inch form factor. It is built for servers and workstations that need fast sequential access and sustained throughput. The drive ships with a tray for direct mounting in compatible Dell bays. Buyers seeking higher capacity per bay should consider larger drives.

Check SAS controller and bay fit

Verify that your system has a SAS backplane or HBA with a free 2.5-inch drive slot. The included tray matches Dell RMCP3 mounting points; other chassis may need an adapter. Confirm the firmware revision is supported by your RAID controller before deployment. Ensure the power and data connectors align with your backplane layout.

Thermals noise and power in normal use

A 10K RPM spindle generates measurable heat and audible seek noise under load. Typical operation stays within enterprise thermal limits when airflow passes over the tray vents. Power draw rises during random I/O bursts but remains consistent with 2.5-inch SAS specifications. Monitor SMART temperature attributes in sustained workloads.
