rucial MX100 was one of the best affordable SSDs on the market last year. This year, Crucial updated the line-up with not one but two drives: the BX100 and the MX200. While the MX200 is the successor to the MX100 and aimed for mainstream market, the BX100 is designed for budget market. The two drives shared the same 16nm NAND but with different controller. Besides the controller difference, the budget drive lacks the hardware-accelerated encryption and the SLC caching that is found on its bigger brother. The SLC caching has its benefit enhancing a drive's write performance but the hardware encryption maybe something that budget users may not care much.
