Recommended model: MX500
 
Critical is a consumer-facing sub-brand of Micron Technology. Micron was founded in 1978 and became the world's second-largest DRAM chip manufacturer in 2012 after Micron acquired Japan's Bilda Semiconductor. Micron and Intel have worked closely together to form an IMFT chip manufacturing company, and its 2011 flash memory chips won the UBM TechInsight 2011 Semiconductor of the Year Award. In 2018, the QLC flash memory jointly developed by Micron and Intel will also be launched. As an SSD manufacturer with its own flash memory particles, the performance of Critical products is also very stable.
 
Critical does not have a flagship M.2 interface for sale, and the entry-level models are divided into the BX series and MX series. Launched in 2017, MX500 has strong performance, occupying the top of the SSD recommendation list of major technology websites such as Anandtech, with read and write performance comparable to Samsung's new 860EVO, and the price is slightly lower than that of 860EVO, providing SATA and M.2 two mainstream interfaces, and the product competitiveness is very strong.
 
The Critical M550 is one of the few major brands on the market with mSATA interface SSD, and its performance is acceptable, but the price is too high, and it is twice as expensive as the Samsung 860EVO with better performance, so it is not recommended to buy it.
