The Crucial X8 is a solid-state drive in the M.2 2280 form factor, launched on October 25th, 2019. It is available in capacities ranging from 500 GB to 4 TB. This page reports specifications for the 2 TB variant. With the rest of the system, the Crucial X8 interfaces using a PCI-Express 3.0 x4 connection. The SSD controller is the SM2263EN from Silicon Motion. Crucial has installed 64-layer QLC NAND flash on the X8, the flash chips are made by Micron. To improve write speeds, a pseudo-SLC cache is used, so bursts of incoming writes are absorbed more quickly. The X8 is rated for sequential read speeds of up to 1,050 MB/s and 1,000 MB/s write.
The SSD's price at launch is unknown. The warranty length is set to three years, which is above average, but shorter than the five years offered by many other vendors. The TBW rating for the Crucial X8 2 TB is unknown, too.
