Samsung has started mass production of industry’s first M.2-based NVMe PCIe solid state drive (SSD). Apt for ultra-slim notebook PCs and workstations, the new SM951-NVMe boasts improved performance with low power consumption.
The SM951 SSD with the help of Samsung’s own controller boasts a sequential data read and write performance up to 2,260MB/s and 1,600MB/s, which in comparison with a conventional SATA-based M.2 SSD, the speed is three to four times faster. The normal M.2 SSD records a read and write speed of up to 540MB/s and 500MB/s respectively.
To achieve such a high read and write speed, the SSD uses four 8 gigabit-per-second (Gbps) lanes (PCIe Gen 3.0 x4) for simultaneous data flow, thus allowing a data transfer rate of 32Gbps and a maximum throughput of 4GB/s.
The 3.73mm thick drive weighs less than 7 grams and processes 300,000 IOPS (Input Output Per Second) compared to 130,000 IOPS rate of AHCI-based equivalent and 97,000 IOPS of a SATA-based SSD.
Furthermore, the drive adopts L1.2 low-power standby mode that consumes under 2mW and allows high-speed circuit to be turned off during hibernation and sleep mode.
The SM951 M.2-based NVMe SSD comes in capacities of 128GB, 256GB and 512GB.
