The Crucial MX100 was a solid-state drive in the 2.5" form factor, launched in May 2014, that is no longer in production. It was available in capacities ranging from 128 GB to 512 GB. This page reports specifications for the 128 GB variant. With the rest of the system, the Crucial MX100 interfaces using a SATA 6 Gbps connection. The SSD controller is the 88SS9189 Renoir from Marvell, a DRAM cache chip is available. Crucial has installed TLC NAND flash on the MX100, the flash chips are made by Micron. To improve write speeds, a pseudo-SLC cache is used, so bursts of incoming writes are processed more quickly. The MX100 is rated for sequential read speeds of up to 550 MB/s and 150 MB/s write; random IOPS reach up to 80K for reads and 40K for writes.
At its launch, the SSD was priced at 80 USD. The warranty length is set to three years, which is above average, but shorter than the five years offered by many other vendors. Crucial guarantees an endurance rating of 72 TBW, a good value.
