Samsung has begun mass producing the new SM1623, a high-performance SAS-interface solid state drive (SSD) using 10-nanometer (nm) class MLC NAND flash memory.
Succeeding the SAS SM1625 SSD, which was introduced in 2012, the new SM1623 has an 800GB density. According to Samsung, compared with the SM1625, which was based on 20nm-class NAND flash, the new 10nm-class SAS SSD delivers the same level of performance while improving productivity by more than 30 percent. It also supports more than a drive write per day (DWPD).
The SM1623 delivers random read and write speeds of up to 120,000 and 26,000 IOPS (Input/Output Operations per Second) respectively. Its sequential read and write speeds are up to 950 and 520 megabytes per second (MB/s).
