Have you written to the pendrive alot? It may have exceeded its write cycles. Pendrives generally have very bad (crappy) NAND flash, 3 or 4 bits per cell, and extremely high write amplification.

Well i don't know what you did with it. But know that USB pendrives use crappy memory; while SSDs use much better 2-bit MLC memory paired with a real SSD controller.

If you used your USB pendrive as linux OS disk; or something similar where the pendrive would see regular small writes; that woul make it fail probably within a month. USB pendrives should be fine to handle large files though.
