Samsung PM981 Phoenix NVMe 1.2 M.2 Solid State Drives

The PM981 M.2 Solid State Drives are Samsung’s latest SSDs that have exceptionally fast read and write speeds thanks to the new Phoenix controller.

The PM981 is fully consist of semiconductor device and using NAND Flash Memory which has a high reliability and a high technology in a small form factor for using a SSD and supporting Peripheral Component Interconnect Express (PCIe) 3.0 interface standard up to 4 lanes shows much faster performance than previous SATA SSDs.

The PM981 provides 256GB, 512GB, 1TB and 2TB capacities. It’s sequential performance is up to 3,200MB/s for read operation and 2,400MB/s for write operation by 4 lanes. It’s random performance is up to 380k IOPS for read and 440k IOPS for write operation by 4 lanes. It could also provide rugged features with an extreme environment with a high MTBF.
