A400 120GB SATA III internal SSD

The Kingston A400 SA400S37/120G is a 2.5 inch internal solid state drive with a 120GB capacity. It uses 3D NAND flash memory and a SATA III interface to deliver sequential reads up to 500 MBps and writes up to 320 MBps. The 7mm height allows installation in slimmer notebooks as well as standard desktop bays.

Suits older SATA laptops

This drive targets users replacing a mechanical hard drive in a SATA based laptop or desktop to gain faster start-up, loading and file transfers. Its shock and vibration resistance supports mobile use. Users who need more than 120GB of space or who require higher throughput than SATA III provides should consider a different drive.

Check your system has a 2.5 inch SATA bay

Verify the host device accepts a 2.5 inch SATA III drive and that the drive bay or caddy accommodates a 7mm height. Confirm the operating temperature range of 0°C to 70°C matches the intended environment. Ensure the power supply can deliver the peak write draw of 1.535W if the system runs sustained heavy writes.

Questions about this item

Does my desktop need a 2.5-inch drive bay and a SATA data cable to install this 120GB A400 SSD?

Yes, the 2.5-inch form factor requires a compatible bay or bracket, and the SATA III interface needs a standard SATA data cable plus a SATA power connector from the power supply.

Will the SATA III interface on this 120GB A400 limit performance if my older laptop only has a SATA II port?

The drive will operate at the SATA II port's lower bandwidth, so maximum sequential read speeds will be below the rated 500 MBps, but the SSD still provides much faster access times than a mechanical drive.

How can I verify the 120GB A400 is delivering its rated performance after installation?

Run a benchmark tool such as CrystalDiskMark and confirm sequential read results approach 500 MBps and write results approach 320 MBps on a SATA III connection.
