The 250GB Crucial BX100 SSD is the value orientated variant of Crucial's M range of SSDs. The BX100 uses the same NAND as its premium MX200 sibling but the BX100 uses a Silicon Motion controller as opposed to the Marvel controller found in the MX range. Feature wise the BX100 is missing SLC caching and there is no hardware encryption (so security frameworks such as windows Bitlocker will operate less efficiently). In terms of I/O performance the BX100 looks promising. Comparing the BX100 and MX100 shows that the newer BX100 may be faster than its predecessor but as yet there are insufficient user benchmarks to draw any definitive conclusions. The BX100 has only just started hitting the shelves so there's plenty of room for price reductions from its already reasonable price tag. I will revisit this review when I have more performance data for the BX100. [Jan '15 SSDrivePro]


Solid State Drive Rankings (Price vs Performance) November 2017 SSD Rankings.

Welcome to our consumer SSD comparison. We calculate effective speed based on real world performance then adjust by cost per GB to yield a value for money rating. Calculated values don't always tell the whole picture so we check them against thousands of individual user ratings. The customizable table below combines these factors and more to bring you the definitive list of top SSDs. Share your opinion by voting. [SSDrivePro]
