The 4TB 850 EVO drive uses 3D TLC (3 bit) V-NAND flash and is capable of hitting maximum sequential read and write speeds of 540 and 520 MB/s, respectively. Random read and random write speeds go up to 98,000 and 90,000 IOPS, respectively. As for the controller, it uses a similar MHX controller to the one used on the 2TB model.
