And after purchasing the laptop, which is standard and USB3.0, was chosen in favor of USB3.0
Further, the by the known route to DealExtreme » Consumer Electronics » Storage USB Flash Drives and chose "Genuine ADATA S102 USB3.0 flash drive" the more it is also compatible with USB2.0 connectors.
Now a little information and pictures:

The first step is to check the amount.
"Screen" of the memory card
Capacity:
* Busy: 8192 bytes or 8.0 KB
* Free Space: 15,797,002,432 bytes or 14.7 GB
For those who do not know a gigabyte = 1024 megabytes
Tested the flash drive at home. Since the special programs I have not. So I took the files (video) size 4.50Gb and copied to the first flash on your computer, then back and timed the a stopwatch.
Calculation formula: volume (in MB) divided by time (seconds) = Speed (MB / sec)
The test result on my laptop (see picture test) my flash drive showed the following results when connected:
to the USB3.0 port
Speed reading is copy data from flash to disk in 81 seconds: 58 MB / sec
Speed write is copy data from disk to memory stick for 140 seconds: 33 MB / sec
to the USB2.0 port
Read speed for 155 seconds: 30.5 MB / sec
Speed write for 220 seconds: 22 MB / sec
As you can see the USB 3.0 interface makes it easier to share files between the flash drive and hard drive computer, and this difference is especially noticeable when reading data from the flash drive.
Of course, I can not make far-reaching conclusions about the advantages of a standard USB 3.0 over its predecessor, the results of my modest test. Yet there are differences, and it is impossible not to notice.
Then checked on the official site of the manufacturer ADATA
so go to the site
For convenience, choose the language.
And look what the specs on the Super Speed USB 3.0 USB Flash Drive (16GB) model S102
Application of a new generation of USB interface allowed us to obtain sequential read speed up to 68 MB / s write - up to 30 MB / s.
performance may vary depending on the set of files, as well as the USB controller in the computer and installed on the system driver.

Total:
Compact, lightweight flash drive with metal housing is designed to store and transfer 16 GB of information. On the back of the flash drive provides the ability to attach a protective cap for the USB-connector, which prevents its loss.
Corresponds to the specs. What is most important to me. Since I often have to flip a decent amount of information.
