Vansuny 256GB USB 3.0 Flash Drive Metal Waterproof Flash Drive USB 3.0 Ultra High Speed Memory Stick, Portable Thumb Drive for PC/Tablets/Mac/Laptop

Love it small no moving sides or parts and works fast enough for me. Fits right on a keychain. I haven't noticed any heat problems. I also have a couple of the Vansuny 500 GB SSD and they work great.

I DO NOT recommend this flash drive. I received a defective drive and could not get help from the company. I wanted to use it to back up my work files. I tried saving the files to the drive and got a copy error message half way through. Copies files were inaccessible. I reformatted the drive and emailed Vansuny through their website for help. NO response. With the drive reformatted, I decided to try again. The drive was super slow and repeatedly stalled while copying the files. I got an error message that certain files could not be copied but I could see a partial list of my files on the drive. So, I tried to copy just the ones that weren’t present. Again, I got an error message but this time it said that the drive was corrupted. When I checked the file manager, now the files were gone and the drive was completely inaccessible. The only thing to do would be to reformat the drive AGAIN. Once again, I emailed Vansuny through their website for help. NO RESPONSE. I DO NOT recommend this drive if you value your files. The drive is unreliable and there is NO customer support.

Muy buen producto

I needed a capacious, high speed USB drive to host a couple of dozen ISO files of various Operating Systems, that I use to build or recover systems. This drive is all metal, fast, water and dust proof, and larger capacity than I really needed. But the price was spectacular. So, why not? So, now I carry all my ISOs, a bunch of extra tools, utilities, and portable programs and its still only half full. What's not to like? Very satisfied with this. Goes with me literally everywhere, and I have no fear just carrying it in the bottom of my pocket. It's 1/3 the size of my previous drive and twice the capacity.

The drive feels very durable, very small so it dosent take up space, nice design, however its not 256GB as advertised, mine came in as 235GB instead, its not really a problem for me but some others it may be.

Works great!

It is slightly the cheapest, seems to work okay as a backup to my backup, but the other reviews are right that it overheats and crashes, disconnecting itself wrong while copying large amounts of data. Speed was as advertised, but it's not very high for this day and age to copy to the drive.

Extremely compact for its storage capacity and has a nice feel
