MFi Certified 512GB Flash Drives 3.0 High Speed 3ni1 USB Stick External Storage for iPhone/PC/iPad/Android/More Devices for Photos and Video

I bought 4 of these to store files and share with other people. I copied the files to the drives fine. When I went to read back the files, they were corrupt or missing. I had this happen to various levels on all 4 of them that I bought. Some had a few files that worked but all of them had major issues with more than half of the files unusable. I formatted the drive and tried again. Same issue. Tried formatting as exFAT and NTFS and still did not work. Returning after wasting way too much time. I was using a standard computer to do this and copying files like I have with any other USB drive (not using a phone or something crazy) and it absolutely would not work. I would advise against buying this to save yourself time and headache.

I copied some files onto the drive and found many missing the next day. Folders were completely empty and the files unrecoverable. I bought this to use with a Windows 11 laptop (the description mentions the drive is "PC" compatible). Once the files were missing, Windows notifications stated the drive needed a "full repair" but could not do so after many attempts. I returned it.

Really bad flashcard

Fake capacity flash. Used to be only no-name flash drives had fake capacity. Now companies put their name on fake flash and provide their own software. 75% of your pictures and videos will be unplayable.

Cannot copy files on it, the files geting corrupt , coping empty folders or damaged files
