Nice description — that behavior (slow when writing to the stick, normal when reading) narrows the fault down. was right to check whether you were on USB 1.1, and says the board supports USB 2.0, so the next steps are about isolating whether it is a port/driver, the flash drive itself, or software on the PC.

Try these checks (one at a time) and report back speeds and results:

  • Plug the pen drive into a rear I/O port (not a front-panel or hub). Front ports are often slower or on a different controller.
  • Test with a different flash drive and with the same drive on another PC to see if the problem follows the stick.
  • Copy one large file (eg. a single ISO) versus many small files. Small-file writes are orders of magnitude slower on some flash controllers.
  • In Device Manager check the USB host controller entry — if it shows a generic host controller, install the motherboard/chipset USB 2.0 driver from the vendor. Reboot after installing.
  • Temporarily disable real-time antivirus and try a copy; some scanners slow write operations.
  • Enable write-caching for the removable drive in Device Manager (if available) but only if you will use Safely Remove Hardware every time — otherwise you risk data loss.
  • If the stick is NTFS, try FAT32 (backup first); some sticks perform better with FAT32 or different cluster sizes.

If you post exact transfer times (MB/s), what port you used, and whether a different stick shows the same issue, we can narrow it further.
