The range of the BX series is somewhat reminiscent of another family of Crucial MX drives - there is a clear continuity between the models, and new items are released less than once a year. All of them are based on 3D TLC NAND memory and communicate using the SATA 3 bus, and the difference between them lies in the format. Under the MX banner there are also compact M.2 solid state drives, while in the BX line everything is limited to more traditional 2.5 format devices.


Typically, BX series drives support wear leveling, advanced hardware error correction, SMART monitoring, flexible power management, and TRIM commands. Linear read and write speeds are limited by the capabilities of the SATA 3 bus and do not exceed 550 – 560 MB. But they have excellent IOPS, which means the drive is quick when working with small files.

The most popular in the series is the Crucial BX500 SATA drive, built on the basis of a low-cost controller from Silicon Motion and a 64-layer flash memory manufactured by Micron. Due to its affordable cost, low power consumption and good read and write performance (approx: 540 and 500 MB / s), it is one of the most popular options for replacing a system hard drive with a faster solid state drive.
