Samsung's latest SSD is remarkably fast and consumes roughly zero standby power


Samsung Electronics has announced that it is mass producing a high-performance, low-powered PCIe SSD designed for use in both ultra-slim notebook PCs and workstations, the SM951.

The SM951 is extremely small for space constrained applications. It comes in M.2 form factor, which is 80mm x 22mm or about one-seventh the size of a standard 2.5" SSD. It also only weighs six grams but can run up to 512GB of capacity.


With a PCIe 3.0 interface on newer laptops and desktops, the SM951 has sequential speeds up to 2,15GB/s read and 1,55GB/s write. That would make it about four times as fast as a current SATA SSD and about 50% faster than its predecessor, the XP941. When it comes to PCIe 2.0 interface, the SM951 also boasts impressive performance with sequential speeds up to 1,6GB/s read and 1,35GB/s write or about three times as fast as the latest SATA SSDs.

What's incredible is that it also uses 50% less power and only consumes about 2mW in standby mode, which is about 97% decrease from the 50mW consumed using a L1 state.

The SM951 is now in production and will be appearing in notebook and desktop systems later this year.

  4. That's nice and all but right now the M.2 format isn't supported very well. I have a M.2 and it has to be physically toggled whenever I want to boot my PC. I contact support in regards to the problem and they basically said they haven't patched a power issue with it yet.
