Capacity and speed

This 120GB 2.5-inch laptop drive spins at 7200 RPM and connects through a SATA 3.0Gb/s interface. An 8MB cache and average seek time of 10.5ms support responsive access for everyday notebook workloads. The bare-drive packaging suits system builders upgrading a single bay.

Thermals and power

Rotational speed of 7200 RPM typically produces more heat and audible seek noise than slower laptop drives, so airflow in the chassis matters. Power draw rises under sustained write loads where average write time reaches 12.5ms. Average latency of 4.17ms reflects the mechanical nature of the platters.

Accessories and software

No cables, brackets or cloning utilities are included with the bare drive. The three-year limited warranty from Fujitsu covers the hardware itself. Installers must supply their own SATA data and power connections plus any mounting hardware the notebook requires.

Questions about this item

How do I install this 2.5" SATA drive in my laptop and which step do people miss?

Slide the drive into the 2.5" bay, connect the SATA 3.0Gb/s data and power cables, then secure it with the caddy screws; the step often missed is tightening those screws so vibration does not loosen the connector.

What maintenance or replacement will the MHW2120BK need later?

No routine maintenance is required; the drive runs at 7200 RPM with 8MB cache, so plan to replace it when SMART attributes show reallocated sectors or after the three-year limited period ends.

What limit appears first under sustained write loads on this 120GB drive?

The 3.0Gb/s SATA interface caps sustained throughput, so sequential writes will hit that bus ceiling before the 7200 RPM platters or 8MB cache become the bottleneck.
