BuiDeni USB 2.0 Flash Memory Drive 256GB with Key (BD/8256)

This is a defective product, too good to be true. I set to copy roughly 100+ GB and had to cancel the operation, because it was going to take over a day. But truthfully I don't think it would ever have happened. I then went in to check the reviews--which I should have done before of course--and the first one that pops up is https://www.amazon.com/gp/customer-reviews/R2FCOKVWVB38ST/ref=cm_cr_dp_d_rvw_ttl?ie=UTF8&ASIN=B076GDD3HV by Tom Nimitz a Top 50 reviewer, and he nails it. I'm returning this product as wholly defective.

Seems to work for a while but then inexplicably loses all data and has to be reformatted. Rolled the dice on this inexpensive model so it is what it is. Would not buy again.

I tried using this drive on two separate macbooks and on a PC. It did not work on any of these. I don't know how this has four stars given that my experience seems consistent with many other one star reviews.

If you're looking to spend money for garbage, then this is the product for you! I ordered 12 and after testing 8 (one of which didn't even work at all) all of them produced error messages of some kind and were horribly unreliable. I was filling them up almost to max capacity for clients and couldn't finish a single one after over 24 hours of troubleshooting. DO NOT BUY.

Don't do it! I bought one of these and was able to squeeze 12.9G of video on it. I know that because when I now try to open I can only read the properties. 12.9 of 259G That is not a mistake This 256G flash drive has 259G capacity.If it is too good to be true......

Product does not work. Have tried repeatedly only for it to fail, not save information, or become corrupted. DO NOT BUY!!!!! Very disappointed.

Does not recognize and when it does it will start downloading my files then stop for no reason and will eject for no reason. Pay extra for the SanDisk

Very slow.
