Lexar has installed 176-layer TLC NAND flash on the NM800 Pro (w/ Heatsink), 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. Thanks to support for the fast PCI-Express 4.0 interface, performance is excellent. The NM800 Pro (w/ Heatsink) is rated for sequential read speeds of up to 7,500 MB/s and 6,300 MB/s write; random IO reaches 1000K IOPS for read and 1100K for writes.
