Usb 3 Speed

Hi
I recently bought a USB 3 flash drive and was curious why I was only getting 32mb/sec read and about 20mb/sec write speed. Could it be that my usb 3 slots are not really usb 3?
Thanks!

It had good reviews on Amazon, here's one of them

Take it for what it's worth. As you can see, 4k write speeds are extremely low, but all of the read speeds are excellent for a flash drive

Are you using the USB 3.0 ports ran by the Intel chipset, or a 3rd party one? That will make a difference. Also, I see you are using the Thermaltake V3, but can you give me a link to the exact one on say, Newegg?

Are you using the USB port on the back of your computer, or the ones in the front of the case? If you are using the ones in the front of your case, they are USB 2.0. If you are using the ones in the back, make sure you have it plugged into one that is actually 3.0, because that motherboard has 2.0 and 3.0 rear USB ports. The 3.0 ports should be blue.

Ok thanks!
I didn't know the blue ones are usb3. I was plugging in the front. It seems from the literature from the intel board that they had 2 in front as well as 2 in the back.
Sure enough I got around 80-85mb/sec read but only about 20 on write still a big improvment
Thanks so much!
The case # is vl80001w2z. I believe it is the intel chipset as I looked in device manager and looked at the drivers I don't know if it means anything (I am a novice) but it did show the intel drivers

The Intel board DOES have front panel USB 3.0, your case, however, does not. If it did, it would come with a single cable with a fairly wide 19-pin connector that would plug into the blue connector on the right/front edge of the board. Most updated cases these days come with a couple of USB 3.0 front panel ports, when you are in the market for a new case, make sure it has that so you can take advantage of it. Glad we got you straightened out though, sounds like those are some pretty decent speeds.

Thanks again for your help
Too bad i hadn't known about that initially, I would have gone with a more expensive case.
