Plextor (styled PLEXTOR) (; ) is a Taiwanese brand (however, a Japanese brand before 2010), best known for solid-state drives and optical disc drives. Company. The brand name Plextor was used for all products manufactured by the Electronic Equipment Division and Printing Equipment Division of the Japanese company "Plextor Inc.", which was a 100%-owned subsidiary company of "Shinano Kenshi Corp.", also a Japanese company. The brand was formerly known as TEXEL, under which name it introduced its first CD-ROM optical disc drive in 1989. The brand has been used for flash memory products, Blu-ray players and burners, DVD -ROM burners, CD-ROM burners, DVD and CD media, network hard disks, portable hard disks, digital video recorders, and floppy disk drives. The brand Plextor was in 2010 licensed to "Philips & Lite-On Digital Solutions Corporation", a subsidiary company of "Lite-On Technology Corporation". Therefore, all the Plextor products since then, especially SSDs, are of a Taiwanese, not a Japanese brand. However, the Japanese company "Plextor Inc.", who originated this brand name, continues, and sells new products under other brands such as PLEXLOGGER and PLEXTALK. Products. In an effort to strengthen its storage leader position, Plextor introduced its first-ever  solid state drives, the M1 SSD series available in 64 GB and 128 GB capacities. Soon after its M1 release, Plextor released the M2 Series 128 GB, and 256 GB, available in 64, using SATA 6 Gbit/s interface, which they claimed to be the first SATA 3 SSD available at the time. In October 2011, Plextor announced the limited edition M2P Series which boast significant increase in speed performance from its M2 Series. Notably, Plextor introduced "ironclad" five-year warranty for its SSD, making them one of the few manufacturers to do so. In addition to the five-year  warranty, Plextor introduced its exclusive TrueSpeed Technology with the M2P series. True Speed Technology is designed to maintain high speed in the real-world computing environment. It consistently works to maintain original performance levels in the long term and without the severe write speed degradation that can occur with other SSDs. In December 2011 and January 2012, Plextor released the M3 and M3 Pro Series in 64 GB, 128 GB, 256 GB, and 512 GB capacities.
