Understanding expected performance helps in identifying when a drive might be underperforming and potentially generating excessive heat. Early benchmark tests of PS2251-07 drives using ATTO Disk Benchmark showed sequential read speeds of approximately 64.5 MB/s and write speeds of approximately 23.5 MB/s. While these are respectable for USB 3.0 drives of that generation, sustained operation at these speeds naturally generates heat. If you experience substantially lower performance accompanied by excessive heat, this indicates a problem requiring attention.

The PS2251-07 is an ultra-high-speed USB-to-Flash micro-controller chip designed to support 3X/2X/1X nm flash memory, with backward compatibility for USB 2.0 and USB 1.1 interfaces. While this controller has generally received positive feedback for its performance and compatibility, a recurring concern among users has become known as the "hot" issue—where these drives run exceptionally warm or even hot to the touch during normal operation.

Check the Preformat option in the MPALL settings. If the flash memory blocks are permanently degraded from heat, input a Target Capacity slightly lower than the drive's original size (e.g., set a failing 32GB drive to 28000MB) to isolate damaged sectors. dedicated computers. When working normally
Flash drive controllers act as tiny, dedicated computers. When working normally, they manage data routing, wear leveling, and error correction codes (ECC). However, a few distinct failure modes can cause a massive temperature spike:

The Phison PS2251-07 (also known as PS2307 or UP307) controller has served as a workhorse for USB 3.0 flash drives across numerous brands and applications. While these drives generally offer good performance and compatibility, the "hot" issue—excessive heat generation—has been a recurring concern for many users.
