Today i got a new USB disk, its labelled a USB 3.0 flash and is capable of reaching speeds of 140 mb/s

When i tested it the best i can get is 20 mb/s

Yes my motherboard has USB 3.0 ports, iv used another flash before and got speeds of up to 80 mb/s
but this flash wont work.

Am i missing something ? or am i just being stupid

thank you in advance

The flash drive is the patriot 32gb usb3

Sounds like a possible mix up between MB/s and Mb/s?

As in MegaBytes vs Megabits?

140Mb/s = ~17.5MB/s

Test it on another computer and see what speeds you get. Sometimes it can be a compatibility issue with a certain USB controller.

Or verify that the product is what it claims, where was it bought, what is the exact model of it? There's a lot of fakes floating around on eBay and other markets.

Well if you obtained read speeds of 140Mb/s then "capable of reaching speeds of 140 mb/s" is true. Read and write speeds are rarely the same, you need to look at the detailed specs, and tested speeds are generally obtained under the best optimal conditions possibly with better hardware.
