120GB MLC SATA III SSD

The HyperX 3K SH103S3/120G is a 2.5 inch internal solid state drive with 120GB capacity. It uses MLC memory and a SandForce controller over a SATA III interface. Sequential reads reach up to 555 MB/s and writes up to 510 MB/s.

Suits OS drive and game library.

The drive fits desktops and laptops that take a 9.5mm 2.5 inch SATA drive. Gamers and general users gain faster boot and load times. The 120GB capacity and MLC endurance limit suit light to mixed workloads rather than sustained heavy writes.

Stand-alone drive with 3.5 inch bracket included

The package supplies the 2.5 inch SSD and a 3.5 inch mounting bracket for desktop bays. No cloning software or extra cables are bundled. The bracket lets you install the drive in a standard 3.5 inch bay without a separate adapter.

Questions about this item

Does my PC need a free 2.5" bay or a 3.5" bracket to mount this 120GB SATA III SSD?

The drive is a 9.5 mm 2.5" unit and the box includes a 3.5" bracket so it fits either bay size.

Will this SATA III drive run at full speed on an older motherboard that only has SATA II ports?

It is backward compatible with SATA II; sequential reads drop to the SATA II ceiling of roughly 300 MB/s instead of the rated 555 MB/s.

How can I confirm the SandForce controller is delivering the rated 85,000 IOPS random read after installation?

Run a 4 KB random-read benchmark such as CrystalDiskMark; a result near 85,000 IOPS shows the controller is performing to spec.
