Got a bunch of unbranded Chinese manufacturered SD cards for free and want to use them as backups. I don’t care what sizes or speeds they truly are but want to know for sure that windows is reporting the correct sizes. Most are 64 gb micro sdxc cards. Person I got them from ordered them from Temu for way cheaper than a regular 64 gig card should cost so I am proceeding with caution.
My only idea is dumping a load of files to fill up them up to their stated sizes and see what gets lost. But that sounds like it’s more of a hassle (and less reliable) than getting a third party software to verify since that’s kinda what they do anyways but more in-depth.
I’m not worried about their reliability since I have so many and going to put the same files on all that 10 would have to fail before I would need to worry.
Any recommendations for either ways to verify or software to check the sizes?
