The modern trend is moving away from Phison’s older USB controllers to ASMedia or in-house designs that use advanced power gating.
For the average user who experiences failure, the ultimate solution is the risky but often effective process of mass production. For the more advanced user or researcher, the controller's programmability opens up more possibilities beyond simple storage. Ultimately, if you value high-speed, reliable, and consistent performance, particularly for running applications or an operating system from a USB drive, it is best to look for drives built around higher-end controllers like the Phison PS2251-08 (PS2308), or even better, a proper external SSD.
The is a widely used USB 3.0 flash drive controller found in popular devices like the Kingston DataTraveler series. While it provides reliable performance for budget storage, users often report the device becoming exceptionally hot during use, which can lead to performance throttling or "firmware panic" scenarios where the drive becomes inaccessible.

Based on community benchmarks and data sheets:
Because budget flash drives lack copper heat spreaders or thermal pads, this constant power draw converts entirely into heat. Within minutes of plugging it in, the plastic or metal casing of the drive can become . If left plugged in, this persistent thermal stress will eventually destroy the controller chip or degrade the silicon bonds inside the NAND flash memory, turning a salvageable software crash into irreversible physical hardware destruction.

If you have a rugged or thick plastic flash drive casing, it acts like a blanket keeping the heat in. If the data on the drive is vital and the drive keeps dropping connection due to heat, carefully crack open the plastic casing using a small pry tool.
If you encounter a “hot” PS2251-07 drive that refuses to format or write, remember: with the correct firmware is your most reliable solution. Just be sure to back up your data first, and never interrupt the mass production process. Why the Phison PS2251-07 Gets Hot Based on
Yes! MPALL supports creating a (Mode 21 or 3) alongside a removable storage partition. This is popular for creating bootable USB drives containing ISO images.
