The Samsung PM893 is a solid-state drive in the 2.5" form factor, launched in August 2022. It is available in capacities ranging from 240 GB to 7.5 TB. This page reports specifications for the 7.5 TB variant. With the rest of the system, the Samsung PM893 interfaces using a SATA 6 Gbps connection. The SSD controller is the MKX (Metis S4LR059) from Samsung, a DRAM cache chip is available. Samsung has installed 128-layer TLC NAND flash on the PM893, the flash chips are made by Samsung. The PM893 is rated for sequential read speeds of up to 550 MB/s and 520 MB/s write; random IOPS reach up to 98K for reads and 30K for writes.
The SSD's price at launch is unknown. The warranty length is set to five years, which is an excellent warranty period. Samsung guarantees an endurance rating of 14016 TBW, a high value.
