Often marketed as a "USB 3.0 High-Speed Controller". Internal Designation: Phison PS2307 or PS2251-07.

If you are trying to make a bootable drive or an ISO-USB, MPALL allows you to set "Mode 21" to create a CD-ROM partition.

Works with various NAND types and capacities.

Firmware crash or internal clock instability. Older firmware revisions (FW version 1.02.xx, 1.03.xx) on the PS2307 are notorious for this.

Users have reported significant variations in speed on identical controllers. For instance, some Kingston DT Elite G2 drives (PS2307) initially reported read/write speeds exceeding , though this was sometimes considered atypical by enthusiasts and might depend on testing environments and specific firmware optimizations. Conversely, a failed reflash with incorrect tools can cause a drastic performance drop, reducing write speeds from over 100 MB/s to as low as 8–20 MB/s.
