Samsung SM961 Polaris NVMe M.2 Solid State Drives

Replaces the Samsung SM951 NVMe M.2 Solid State Drives

The Samsung SM961 M.2 Solid State Drives are exceptionally fast storage drives that offer read and writes speeds of up to 3200 and 1800 MB/s respectively!

The SM961 boasts outstanding performance, supporting both PCIe 3.0 x4 interface. They can read and write sequentially up to 3200 MB/s (megabytes per second) and 1800 MB/s respectively based on PCIe 2.0. This performance level is approximately five times faster than that of the latest SSD with a SATA interface and about twice as fast as the previous SM951, its predecessor. In addition, the new SSD’s random read and write speeds reach up to 450,000 and 320,000 IOPS (inputs / outputs per second) respectively. These figures vary based on the capacity chosen, see the specifications table below for exact information.

Features

Incredibly fast M.2 SSD
NVMe Host Controller Interface
Offers sequential read and write speeds of up to 3200 and 1800 MB/s
Available in 128, 256, 512GB and 1TB
L1.2 power state for reduced power consumption

In addition, the SM961 continues 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 SM961’s power consumption is drastically reduced – to just 2.5mW, about a 97 percent decrease from the 50mW consumed using a L1 state.

Samsung’s SM961 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 SM961 lineup consists of 1TB, 512, 256 and 128 GB SSDs.

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.
