The Crucial MX500 is a solid-state drive in the 2.5" form factor, launched in January 2018. It is available in capacities ranging from 250 GB to 2 TB. This page reports specifications for the 500 GB variant. With the rest of the system, the Crucial MX500 interfaces using a SATA 6 Gbps connection. The SSD controller is the SM2259H from Silicon Motion, a DRAM cache chip is available. Crucial has installed 128-layer TLC NAND flash on the MX500, the flash chips are made by Micron. Please note that this SSD is sold in multiple variants with different NAND flash or controller, which could affect performance, the "Notes" section at the end of this page has more info. To improve write speeds, a pseudo-SLC cache is used, so bursts of incoming writes are absorbed more quickly. The MX500 is rated for sequential read speeds of up to 560 MB/s and 510 MB/s write; random IO reaches 95K IOPS for read and 90K for writes.
At its launch, the SSD was priced at 140 USD. The warranty length is set to five years, which is an excellent warranty period. Crucial guarantees an endurance rating of 180 TBW, a relatively low value compared to other SSDs.
