This approach lowered the barrier to entry for USB drive manufacturing. Companies did not need deep engineering expertise to produce high-quality drives; they simply needed to source the PS2251-68 controller and pair it with NAND flash dies (often sourced from major manufacturers like Samsung, Micron, or Toshiba). Consequently, the market was flooded with affordable, high-speed USB 3.0 flash drives. The PS2251-68 became the "engine" for countless generic and branded drives found on Amazon, AliExpress, and in retail stores globally, effectively standardizing the performance expectations for mid-range portable storage.
Another tool frequently used to flash or create CD-ROM partitions on PS2251-68/PS2268 drives is the UPTool.
