256GB USB Drive, Coousyu USB Memory Stick Waterproof Storage Thumb Drive with Keychain

This is a great little flash drive. It is made of a solid metal material making it a very durable and stylish addition to my keychain that I don'thave to worry about breaking. I really like the compact and clean design. In today's digital age it is really convenient to always have a thumb drive at the ready. I would highly recommend this as an increasingly necessary addition to anyone's keychain.

Would be great if it didn't take literal days to upload files.I was shocked by all the good reviews I found when I checked to see if anyone had the same experience I had. I'm trying to store an 11 GB file on the drive and was told it would take a full day to transfer - oh nevermind, its updated so now it'll ONLY take 22 hours. These aren't even the largest files I want to store on this.

I use them to transfer Video Files and they are Great!!!!!! Would purchase again..

I bought this usb to back up/replace an old hard of mine. The drive keeps saying it has a disk error and won’t hold more than about 50gb worth of data without giving a corrupted disk error. I tried to perform a low level format on the drive but it still has issues. It is possible that I just got a lemon but since I haven’t used this brand before I can’t say for sure.

holds a lot of data

Not sure what all the glowing reviews are about. Any time I try to copy over more than 64 BG of Data to the drive it fails. I ran a test using a Flash Testing tool called H2testw and it fails to write past this amount. Maybe I got a "lemon" as well but buyer beware!

As soon as I transferred my files onto this hard drive it corrupted all of them. I tried it multiple times and every time it would corrupt the files and make them inaccessible

Waste of money, It didn't work, or is locked to use or the computer doesn't recognize the USB. after a while is hot and burn to disconnect.
