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.

If your drive continues to overheat instantly upon being plugged into multiple computers without transferring data, it likely has a short circuit on its main 5V-to-3.3V power regulator line. In this scenario, the chip is physically damaged, and further electrical exposure can permanently destroy the underlying NAND flash memory cells. To help narrow down the issue, let me know: In this scenario, the chip is physically damaged,
