The original memory stick is also called "crutch" and the fake one is called "grouping stick".
The assembly rod was not made by Sony, but the chip was made by Sony and spliced by a third party other than Sony. The chip of Sony memory stick bought by a third party is spliced with the shell of Sony memory stick. Due to processing technical problems, the memory stick has a short life and is easy to damage data.
Distinguish the authenticity of a memory stick: press the "triangle" key where games, music, videos and pictures are selected. If it shows "Support" as genuine memory stick, if it shows "Unknown" as false, group and expand memory stick.
The stick in the group doesn't have Sony's electronic verification code, so it will show "unknown" and the stick will show "support". I just used a 16G (high-speed) group and a 2G (ordinary) line to measure the speed with psp memory chips. My club is more than three times faster than the league, and it only took nine months. This is the difference.
In addition, the memory stick does not rule out data loss due to improper use, but generally it will not lose data, unless your memory stick is poisoned or other human factors, the memory stick can read and write data normally.
I suggest you buy a crutch. Don't worry, crutches are guaranteed for ten years at high speed and five years at low speed!
Please ask me for help about PSP, and I will give you a satisfactory answer in time!
