"Hi Guys, I have just bought a Toshiba UHS3 128GB Micro SD Card. At the moment, I am getting poor speeds using the SD card on my PC, with a read of 35.74MB and a write of 10.72MB. This is a card that is supposed to have read speeds up to 90MB/s. I hope that I would get a lot faster than the speeds I am getting on the PC. Am I unrealistic, or could there be an issue with my tablet? Would a factory reset help anything?"

Most card readers also offer to write capability, and together with the card, this can function as a pen drive. If you have the right SD card reader, you can gain:

Fix 2. Convert SD Card/USB from FAT32 to NTFS

Another way to fix a slow SD card is by converting FAT32 to NTFS without losing data. A FAT file system is often used in removable storage devices, such as digital cameras, Smart TVs, and other portable devices. But it has many limitations:

  • FAT32 only supports files of up to 4GB in size and volumes of up to 2TB in size
  • FAT32 isn't a journaling file system, which means corruption can happen more easily
  • FAT32 doesn't support file permissions

While NTFS supports very large files, restores consistency by using a log file and checkpoint information, supports file compression when running out of disk space. You can convert FAT 32 to NTFS with the help of EaseUS Partition Master Free. This free tool allows you to convert the drive from FAT32 to NTFS without formatting directly.
