Plextor PX-128M5S Solid State Drive

The Plextor PX-128M5S is a solid-state drive (SSD) part of the high-performance M5S series, originally released by Plextor, a brand with Japanese photographic and optical roots that transitioned into digital storage. This specific unit was manufactured in July 2013 and utilizes the SATA III interface for high-speed data transfer.

The brand's digital storage division was for a long time managed by Lite-On Technology Corporation, a major Taiwanese electronics manufacturer, specifically through its 'Lite-On IT Corp' subsidiary. This relationship solidified the brand's reputation for using high-quality components such as Marvell controllers and Toshiba NAND flash memory.

In terms of ultimate ownership, Kioxia Corporation (formerly Toshiba Memory Holdings Corporation) acquired the SSD business of Lite-On, including the Plextor brand, in 2020. This acquisition brought the long-standing storage brand back under the umbrella of a Japanese-headquartered global leader in flash memory and SSD technology, ensuring continued support and integration with cutting-edge memory manufacturing.
