SAMSUNG ST750LM022 750GB 5400 RPM 8MB Cache SATA 2.5" laptop hard drive

Capacity and form factor

The Samsung Spinpoint M8 ST750LM022 provides 750GB of storage in a standard 2.5-inch laptop form factor with a 9.5mm thickness. It connects through a SATA 3.0Gb/s interface and uses an 8MB cache to handle everyday workloads such as operating system files, documents and media libraries. The bare-drive packaging makes it suitable for system builders or upgrade projects where retail accessories are not required.

Sustained workload behaviour

The drive spins at 5400 RPM with an average seek time of 12ms and average latency of 5.6ms, delivering consistent throughput for sequential reads and writes during extended file transfers or backup jobs. Native Command Queuing support helps optimise command order when multiple requests are queued, reducing head movement overhead under heavy multitasking. The 750GB capacity remains fully addressable after a DoD 5220.22 M compliant erase, though up to 25 bad sectors may be present on some units.

Thermals noise and power draw

SilentSeek technology and NoiseGuard acoustic management keep operational sound low during typical office or home use, while Load/Unload head technology parks the heads safely when the drive is idle. The 5400 RPM spindle speed contributes to modest heat output and power consumption compared to faster-spinning drives, allowing the unit to run within the thermal envelope of most thin-and-light notebooks without additional cooling measures.
