I wouldn't risk holding anything important on a cheap drive - you get what you pay for. I've lost ALOT of music+graphics+lyrics etc ive made because i had them stored on cheap thumb drives and they quit working

but also you absolutely shouldn't touch temu with a 10 foot pole. There's several personal lawsuits + class actions against them right now. They sell TF out of your information (that's why they're willing to lose money on products.) and people have even had their bank accounts drained and it was proven to tie back to Temu.

But yeah, I'd definitely go with amazon instead and make sure to do detailed research on which one youre getting - see if people have reviewed it and said it died on them. But - your best bet is buying one external HD vs. a pile of thumbs. a drive has better survival rates.

But, even that - if the grid went down, anything digital ceases to exist. It's worth printing at LEAST a folder (if not a box) worth of stuff that NEEDS preserved.
