Hello to everyone, Okay so everything is working as it should, until yesterday when i had to transfer a 47gb file. I coundn’t becuase the file system was FAT32, so i instinctivly format it to exFAT and i had no problems moving the file to my stick, but i notices that the speeds never got over 30mb/s, I ran CrystalDisk and i got 33mb/s write and 30mb/s read. I though i did something wrong so i formated it again but this time i selected NTFS, still the same. I plugged it in different usb 3.0 slots. Same thing. Then i used google ofcource, and i read a post here, that i have to restore some structural data on the drive becuase when you format the stick you erase that too. Also i read about secure erase with parted magic, but i never got parted magic to run, i get an error half of the loading.

Drives 32GB and larger are manufactured as exFAT so its strange that your’s was FAT32. A utility that I’ve used when formating a drive is named RMPrepUSB. It may help you reformat the drive to a faster speed.
Another option is to return the drive for a replacement.
When a USB 3.0 drive maxes out right around 30 to 33 MB/s, it is a classic sign that the drive is bottlenecked by USB 2.0 speeds. Even though you are using a USB 3.0 port, the system is treating it like an older, slower device. You can follow the step-by-step fixes:
1. Download the official SD Card Formatter tool (created by the SD Association).
Open the program and select your SanDisk drive.
Choose Overwrite format (instead of Quick Format).
This completely resets the flash blocks and restores proper cluster alignment.
2. Change the Windows Device Policy
Right-click the Windows Start button and open Device Manager.
Click the arrow next to Disk drives to expand the list.
Right-click your SanDisk drive and select Properties.
Go to the Policies tab, select Better performance, and click OK.
Note: You must always click “Safely Remove Hardware” in your system tray before unplugging the drive.
