Plextor has added the S1 series to its MLC SSD product line, which will be available only in Southeast Asia because of the limited quantities. The S1's core components include Toshiba's A19nm Toggle Mode MLC NAND flash memory, as well as the SMI's SM2246 controller. The S1 series promises to provide performance up to 510/440 MB/s in sequential read/write and 74K/79K IOPS in random read/write, respectively.

Plextor's S1 series SSDs are available in two interface specifications: 2.5-inch (S1C) and M.2 2280 (S1G); with two different storage capacities: 128GB and 256GB.
