Product Overview

Main Features
  • Solid state drive
  • 256 GB
  • internal
  • M.2 2280
  • PCI Express 3.0 x4
The SM951 boasts outstanding performance, supporting both PCIe 3.0 and PCIe 2.0 interfaces. For use in the latest ultra-slim notebooks, it can read and write sequentially at 1,600MB/s (megabytes per second) and 1,350MB/s respectively based on PCIe 2.0. This performance level is approximately three times faster than that of the latest SSD with a SATA interface and about 30 percent faster than that of the Samsung XP941, its predecessor. In addition, the SSD's random read and write speeds reach up to 130,000 and 85,000 IOPS (inputs/outputs per second) respectively.

For ultra-slim notebooks and workstations wanting to adopt the PCIe 3.0 interface, the SM951 can read and write sequentially at 2,150MB/s and 1,550 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 450MB/s per watt for sequential reading and 250MB/s per watt for sequential writing.

In addition, the SM951 is the first SSD to adopt the L1.2 low power standby mode as defined by PCI-SIG (the PCIe standards body). By embracing the L1.2 level of standby operation, the SM951's power consumption is drastically reduced - to under 2mW, about a 97 percent decrease from the 50mW consumed using a L1 state.

Samsung's SM951 comes in the M.2 form factor, which is only about one seventh the size of a 2.5 inch SSD. Also, it weighs approximately six grams. The drive's compactness is well suited for most notebook PC designs, freeing up space for other components including the battery.
