Samsung PM961 Polaris NVMe M.2 Solid State Drives

The Samsung PM961 M.2 Solid State Drives offer lightning read and writes speeds at a very competitive price.

Features

  1. Samsung Polaris Controller
  2. Incredibly fast M.2 SSD
  3. NVMe 1.1 Host Controller Interface
  4. Sequential read and write speeds of up to 3000 and 650 MB/s *
  5. Random read and write 4KB of up to 360,000 and 150,000 IOPS *
  6. Sequential read and write speeds of up to 3000 and 1700 MB/s †
  7. Random read and write 4K of up to 360,000 and 330,000 IOPS †
  • *PM961 M.2 128GB only
  • PM961 M.2 1TB only

The PM961 NVMe boasts outstanding performance, supports PCIe 3.0 (x4) interface. For ultra-slim notebooks and workstations wanting to adopt the PCIe 3.0 interface, the PM961 can read and write sequentially at 3000 MB/s and 1150 MB/s respectively, which would provide approximately four times faster sequential reading performance compared to current SATA SSDs. With a PCIe 3.0 interface, the drive achieves substantially higher energy efficiency, requiring only about 450 MB/s per watt for sequential reading and 250 MB/s per watt for sequential writing, which translates into a more than 50 percent improvement in performance per watt over that of the XP941 SSD. In addition, the new SSD’s random read and write speeds reach up to 360,000 and 280,000 IOPS (inputs / outputs per second) respectively.
