Samsung has presented a new M.2 based solid-state drive that is known as SM951. The new SSD is both fast and small-sized and given its price it may be a perfect choice for first-time SSD users.
The new SM951 solid-state drive supports PCI-E 2.0 and PCI-E 3.0 and measures 22 x 80 mm. It uses the NVMe protocol and is based on 10 nm MLC NAND flash memory. There are two capacities available as of now – 128 GB and 256 GB. The 128 GB model reaches 2000 MB/sec of read speed and 650 MB/sec of write speed, while the 256 GB model is faster at 2150 MB/sec while reading and 1260 MB/sec while writing. The 128 GB model also reaches 300 000 IOPS while reading and 83 000 IOPS while writing. The 256 GB version is again faster at 300 000 IOPS while reading and 100 000 IOPS while writing. In addition to all this the Samsung SM951 solid-state drive is extremely energy-efficient – it needs 1W of energy per 250 MB/sec while writing and per 450 MB/sec while reading, which is 2 times less compared to its predecessors.
The SM951 solid-state drive costs USD 132 for the 128 GB model and USD 207 for the 256 GB version.
