USB 3.0 low rate transfer

[santiagobloom]

Hey everyone, I hope you could give me some help with this. I own a Lenovo Notebook bought on January 2013. Two 3.0 usb ports and a single 2.0
I bought a Kingston DT111 3.0 8gb and I have two problems with that. First, the pendrive appears to be only 7,3 gb, and then the data transfer speed goes up to 5mb/s. I formatted the USB and still the same. The drivers on W7 home basic also appear to be ok. What is your opinion? Thanks.

As far as actual space goes the 7.3GB is probably correct. This link explains it pretty well - http://answers.yahoo.com/question/index?qid=20100907092214AA5Cud4
I have a 32GB flash drive but in Windows Explorer and disk management it shows up as a 29.8GB drive. Regarding the speed, are you transferring a single large file (would be slower) or several small files (should be faster)?

Thanks. About the 7,3 gb I guess I stopped caring. I tried formatting and Installing the latest (aledgely) usb 3.0 drivers for my notebook, and the flashdrive is 3.0 too, and still nothing, about 10 mb/s transfer rate.
