Part 1: What is the Phison PS2251-07 / PS2307?

Before solving the heat issue, we must understand the hardware. The Phison PS2251-07 (also known as PS2307) is

Preventive practices

• Avoid filling the drive to near capacity (leave spare over-provisioning).
• Use drives for appropriate workloads: cheap USB sticks are for light file transfer, not as continuous backup targets.
• Regularly back up important data; hot behavior can precede failure.

Selecting a replacement (recommendations)

• Prefer drives from reputable brands with metal enclosures and explicit thermal specs.
• For heavy sustained transfers, choose USB drives or portable SSDs with active/passive cooling (aluminum body) and controllers designed for sustained I/O.
• Check reviews for sustained write performance (not just burst).
