Product information: SM951 512GB M.2 PCI-e Gen3 8Gbps x 4 AHCI Solid State Drive (MZHPV512HDGL-00000) The SM951 boasts outstanding performance, supporting both PCIe 3.0 and PCIe 2.0 interfaces. They can read and write sequentially at 1,600 MB/s (megabytes per second) and 1,350 MB/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 new 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 2,150 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 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: Some M.2 motherboards only support SATA 6Gbps speeds or PCI-e x 2 lanes. You need to make sure your board supports PCI-E x4 Lanes to get the full speed from this SSD. Specification: - M.2 PCI-E 3.0 (x4) interface or M.2 PCI-E motherboard slot - MLC NAND - Read Speed: 2150MB/s - Write Speed: 1500MB/s - IOPS: 140k/85k - Warranty: 2yr. My god it's fast! Bought this for my new X99 motherboard. I love the fact that it fits straight to the board and doesn't block airflow to the GPU's. And the speeds from it are amazing.

The Samsung SM951 is only available to OEMs (system integrators, system builders, etc.) in capacities of 128GB, 256GB, and 512GB. The drives come in the M.2 2280 form factor and natively supports. Discover the latest features and innovations available in the SSD 950 PRO NVMe 512GB. Find the perfect Memory & Storage for you! * Based on internal 10GB file power consumption tests using a 512GB capacity 850 PRO and 950 PRO. Results may vary based on the user environment. This cutting-edge V-NAND-based NVMe SSD supports PCI Express.
Crystal disk mark shows 2644MB/s read and 1541MB/s write. I'm using mine as an OS drive and to install the latest games I'm playing. Once I've finished with a game I install it to my normal steam or Origin directories on my other SSD's. Game loading times are massively quick now and windows runs like a dream.
For the price of this drive you really can't go wrong.
