I got a cheap 64GB card from eBay for like $10 for my Venue 8 Pro Windows 8 tablet, and after installing something to a folder or copying large files to any folder, that folder just gets corrupted.
I've permanently mounted it to a folder on my C drive, and say after downloading a torrent to the Downloads folder (on it) or downloading a game from Steam (where Steam is installed on the SD card), the Steamapps folder just gets corrupted. I can't delete these corrupted folders.
I've analyzed that it happens after a lot of writes to the SD card and the only way to fix it is to format the card. The FS is NTFS. Is this happening because this is a cheap SD card, or is there any other reason?

Here's the title of the SD card on eBay if it gives any info:
