Samsung's drives carry part number PM853T SSD and will be offered in 240GB, 480GB, and 960GB capacities. All versions of the drive are designed for high levels of random IOPS performance and QoS that are essential in the data center.

Samsung says that the new 3-bit SSDs bring a 30% increase in manufacturing efficiency compared to SSDs using 2-bit NAND. The new drives use 10nm class 3-bit NAND flash and promise sequential read speeds of 530 MB/s with sequential writes at up to 420MB/s. IOPS performance of 90,000 IOPS random read and 14,000 for sustained writes is promised. Pricing on the drives is unannounced.
