Samsung Electronics has officially announced the start of mass production of PCIe M.2 SSD, allowing ultra-fast read/write speeds and with the M.2 form factor bringing modest power consumption. The new SM951 series focused on the use of ultra-thin notebooks and workstations, plus, in addition to PCIe 2.0 interface they support the current standard PCI Express 3.0, which significantly expands the scope of their application. When connected to PCIe 2.0, the SM951 promises sequential read and write speeds at up to 1600/1350 MB/s, respectively, which is very good.
At the same time, the maximum performance mode, random read / write clocks in at 130 000/85 000 IOPS respectively. In turn, connecting to PCIe 3.0 allows for sequential read and write data with speeds up to 2150/1550 MB/s, respectively, bringing better performance than SATA Interface SSD, while also providing energy efficiency. Suffice it to say that to read or write 450 MB or 250 MB of information here is consumes just one watt.
In the solid-state storage SM951 used proprietary flash memory MLC NAND, produced by Samsung’s advanced technological standards of 10-nm-class, and the size of the M.2 SSD format is only 80 x 22 mm and weighs about 6 grams. Versions of the PCIe M.2 SSD with varying capacities are expected; 128 GB, 256 GB and 512 GB, however, their value is not yet reported.
