Did you not install all the drivers for the MB ?  If not, you should.
Then you should also check with another USB3 device or test that USB3 device on another machine with USB3 to check if there is a difference.

I will urge you to test it again on another machine with USB3 to see if it performs any different. Same test you used here.
You may want to inspect these tests and compare.
http://www.whoratesit.com/Verbatim-Store-n-Go-V3-USB-30-16GB/Rating/1347

Depending on the file sizes used, even Verbatim only claims 60/12

Quote
The ATTO results for the Store n Go are broadly in line with the CrystalDiskMark scores and at 72/46 MB/s come in at reasonable levels especially considering Verbatim only claims read/write speeds of 60/12 MB/s.

That's all you can get from that stick.
