Samsung's SM951-NVMe delivers an unmatched level of responsiveness that far surpasses SSDs with a SATA 6Gb/s interface.

The SM951-NVMe solid state drive is the leading storage drive in the industry - featuring a NVMe PCIe Gen.3.0 interface. It sequentially reads at 2,260MB/s (megabytes per second), an example of ultra-fast speeds that are 3-4 times faster than those of a typical SATA-based M.2 SSD.

Samsung's SM951-NVMe SSD technology powers the HP Z Turbo Drive G2. It complements the portfolio of the HP Z Turbo Drive G1, designed using the Samsung XP941 SSD.

In the Samsung SM951-NVMe, the technology is designed into an M.2 form factor, with a thickness that does not exceed 4 millimeters, (3.73 millimeters maximum, when equipping chips on both sides of the board). This is less than the thickness of two nickels stacked on top of one another. The drive also weighs less than 7 grams, which is only one tenth the weight of a 2.5" SSD.
