Value SSDs at the 120 GiB capacity are very popular nowadays, since they are affordable and have enough space to use them as a fast boot drive, while you can use a standard hard drive as a secondary drive to store your data files. Today, we are testing the Corsair Force LS, a value 120 GiB SSD, and comparing its performance to a very popular 2.5” SATA SSD, the Kingston SSDNow V300 120 GiB SSD.

The Corsair Force LS SSD uses 2.5” form factor with a height of 7 mm, SATA-600 interface, and can be found in 60 GiB, 120 GiB, 240 GiB, 480 GiB, and 960 GiB capacities. The part number of the 120 GiB model, which is the one we are testing, is CSSD-F120GBLSB. It has 128 GiB of memory inside, but is sold as 120 GiB, since 8 GiB is reserved for overprovisioning, used by the garbage collection and wear leveling mechanisms of the unit.

In our tests, we will compare the performance of the Force LS 120 GiB against the Kingston SSDNow V300, with the same capacity, which is one of the best-selling value SSDs on the martket.

Before proceeding, we highly suggest that you read our “Anatomy of SSD Units” tutorial, which provides all the background information you need to know about SSDs.

In the table below we compare the Corsair Force LS 120 GiB with the Kingston SSDNow V300 120 GiB. Both units use a SATA-600 interface, 2.5” form factor, and MLC memory chips.
