Samsung 128GB M.2 PCIe_ACHI SM951 SSD (FFT MLC NAND)

The SM951 boasts outstanding performance, supporting both PCIe 3.0 and PCIe 2.0 interfaces. It can read and write sequentially at 1,600MB/s (megabytes per second) and 1,350MB/s respectively based on PCIe 2.0.

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. The drive's compactness is well suited for most notebook PC designs, freeing up space for other components including the battery.
