Crucial BX300 480Gb SSD Storage Review

Admin Storage 151


We’ve reviewed most of Crucial’s SSD product line over the years and it’s given us some good insight into their market placement and development. We have recently reviewed the MX300 1Tb SSD, effectively the third generation of their MX series, and it gave a good score and representation of Crucial. Now we are on to the third generation of the BX series, the BX300, which was released recently.

We have had the BX300 480Gb on the test bench for a while, so we have had a good run of its performance. With 2018 just starting off, we are going to see a lot of offers tempting you into your next SSD upgrade, let’s find out if the Crucial BX300 is going to be one of them.

The new BX300 uses Micron’s first-generation 3D MLC flash, an entry-level BX series with 3D MLC. Despite supporting features such as encryption, Crucial have not included support for this, not uncommon in lower price point products. Noticeably absent from the BX300 range is a 1TB model, hopefully coming in the near future.

Strangely, the range includes a 120Gb model most likely targeted at the laptop market, for anyone looking for a quick and effective upgrade.
