Is it better to use exFAT, NTFS or FAT32 for the usb drives?
There is no difference in speed between FAT32, exFAT or NTFS formatted drives. If your thumb drive is less or equal to 4GB we recommend using FAT32. Use exFAT (recommended) or NTFS if you want the cache file sized more than 4GB (make sure that the drive has a good write speed, otherwise disable the “write-cache” option for this drive to prevent “Windows Delayed Write Failed” errors).
