Samsung unveils NVME-SSD with PCI-E 3.0 x4 interface




Samsung has the arrival of a NVMe-SSD with PCI-E 3.0 x4 interface reported during its SSD Global Summit. The Non-Volatile Memory Express interface should provide higher speeds and significantly lower fuel consumption compared to SATA models.

Samsung supplies the SSD with the model number “SM951” in eM.2 and 2,5 ‘-variants, is designed for ultrabooks and will only be supplied to manufacturers. According to Anandtech Samsung SSD has already supplied to OEM’s, but is waiting for its first products.’s sequential read and write speeds of the drive are respectively 1600MB / s and 1000MB / s and according to Samsung two to three times faster than current SATA models for ultrabooks., the number of IOPS would 130,000 and 100,000, respectively, in true reading and writing and consumption in idle mode would be a relatively low 2mW.

The performance gain is attributable to the use of the PCI-E 3.0 x4 interface in conjunction with nvm-express , which stands for Non-Volatile Memory Express. This standard is the successor to SATA and is made for SSD’s. Nvme uses PCI-Express interconnects and the controller makes significant optimizations for power possible. The SM951 is not the only SSD with nvme and PCI-E 3.0 x4 that Samsung SSD in his Global Summit showed. The company also comes with the SM1715: an enterprise card with a storage volume of up to 3.2 TB.

Samsung also comes with the 845 DC Pro series for business use. These traditional SATA SSDs utilize 3d v-nand and Samsung focuses on longevity. In contrast to last week’s 850 Pro, the 845 DC Pro series about 3d flash memory of the first generation, with 24 stacked layers instead of 32. Drives come in capacities of 800GB and 400GB on the market. The prices are not yet known.
