As we said before, installing the operating system at an SSD (solid state drive) instead of a hard disk drive is the best way to have a visible speed improvement on your computer, because one of the tasks that takes more time is loading programs. While 120 GiB SSDs are still the most popular due to its low cost, 240/250 GiB units are becoming more preferred.

Today, we will test the Crucial BX100 256 GiB SSD, targeted on users that are looking for an SSD with a good cost/performance ratio. The Crucial BX100 can be found in 120 GiB, 250 GiB, 500 GiB, and 1 TiB capacities.

The model we tested has 256 GiB total memory, but it is sold as 250 GiB because 6 GiB are reserved for “overprovisioning”.

Crucial, by the way, is a subsidiary of Micron, a traditional memory manufacturer. In our tests, we will compare the performance of the BX100 to the Corsair Neutron XT with similar capacity.

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 compared the tested units. Both use SATA-600 interface and the 2.5” form factor, with 7 mm height, and MLC memory chips.

We researched the prices on the day that we published this review. In the table below, we provide a more in-depth technical comparison between the two drives.
