JUANWE 50 Pack 2GB USB 2.0 Flash Drive Bulk Pack Memory Stick Swivel Thumb Drives Pen Drives - Black

I got a 20pk of the 32gb drives and they don't seem to go through much QC.They all READ data just fine. It's writing that's an issue. More than half of them have serious issues with writing, a cache filling up, the controller failing, something is causing I/O to be blocked. Tested with other files, other brands of USB sticks and sizes, and on other systems and they were consistently slow at random and would table consistent write speed.I was hoping for a cheap stash of USB drives to build a dev/test Gluster cluster but aside from the failure rate, they're a serious bottleneck if you can even use them. You get what you pay for I guess.

Drives are reasonably quick 8Mb/s. I loaded all with content - found only one that was dead.

these were great for putting 3,000 plus photos on and handing out to a large group of people.

I purchase flash drives by the bulk for the office. Some have a lot of defected flash drives and some very little defected. So far I haven't received any defected ones from anyone. I guess it's safe to say that these are a good buy.

Purchased 50 of these for work. No issues so far. Build is standard and none have fallen apart. No defective units noted. No viruses found. Overall good price for the number of units.

Works as it should good quality. If only I could use these in my aging brain.

Seem great so far. We use these in somewhat of a disposable manner so cannot speak to long term durability.

not a single problem with these. work great, highly recommend for those of us that like to keep these on our key rings.
