I own 4 of these, bought from Aliexpress for >$20. This seems to be sold by the official MOVE SPEED store on Temu.
It's not the fastest card—write speed is around 40MB/s—but it's 17 bucks. I legally ripped my 4k Akira Bluray with 7.1 Dolby Atmos, put the 80GB file on one, and it played fine. And also 24/192 FLACs. So these fit my use case, and is almost the same as the Sandisk 400GB cards.
My Samsung Evo Pro+ 512GB writes at ~80MB/s but cost 3x of this MOVE SPEED. (both using the OEM card reader on my PC)
Edit: 3 hours left for free shipping. Also free returns within 90 days
Never heard of temu, looks like a wish clone.
Whats their refund policy like? I'll never trust chinese sourced memory until I do a fill test 1st hand…
