Samsung SM951 NVMe M.2 Solid State Drives

- Replaces the Samsung SM951 AHCI M.2 Solid State Drives- Replaced by the Samsung SM961 Polaris NVMe M.2 Solid State Drives

The Samsung SM951 M.2 Solid State Drives are currently the fastest commercially available SSDs, offering read and writes speeds of up to 2150 and 1550 MB/s respectively!

The SM951 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 SM951 can read and write sequentially at 2,150 MB/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 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 300,000 and 100,000 IOPS (inputs / outputs per second) respectively.

Features

  1. Incredibly fast M.2 SSD
  2. NVMe Host Controller Interface
  3. Offers sequential read and write speeds of up to 2150 and 1550 MB/s
  4. Available in 128, 256 and 512GB
  5. L1.2 power state for reduced power consumption

The SM951 is the first SSD to adopt the L1.2 low power standby mode (which allows all high-speed circuits to be turned off when a PC is sleeping or in hibernation) 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 (80 mm x 22 mm), which is only about one seventh the size of a 2.5" SSD. Also, it weighs approximately six grammes. The drive's compactness is well suited for most notebook PC designs, freeing up space for other components including the battery. The SM951 lineup consists of 512, 256 and 128 GB SSDs.

Please Note: While numerous motherboards support M.2 drives, they often restrict the amount of data that can be moved to and from the drive via the M.2 interface resulting in slower than expected speeds (around 50%) due to running at only PCI-e 2 speeds. To enable these drives to work at full speed, the M.2 interface on your motherboard must support PCIe 3.0 and have four lanes (many only support two at this time). The new x170 chipset from Intel is able to accommodate these faster speeds.

PLEASE NOTE: These M.2 drives are compatible with Type M keys only. Please check your hardware is compatible with this type. There is also a Type B key which these drives will not connect to.

Windows 7 Users: Please note that Windows 7 users may experience difficulties installing a fresh copy of Windows 7 directly onto a NVMe M.2 SSD. This is due to Windows 7 not having a driver for the M.2 drive. Microsoft have provided a hotfix and instruction to help install Windows 7 on a NVMe drive.
