My source is when the windows box comes up and tells you how much longer or how big the files are or from where to where you are sending the files. It's the only thing I can find that will tell me anything. Do you know of any utilizes that will show me how fast things are going between drives? I'm really sorry about the spelling, my keyboard isn't working at spelling these days. LOL

By source I meant what drive you were transferring from/to the USB 3.0 drive. Was it an internal disk or...?

Has anyone gotten their USB 3.0 speed up to at least 3GB/sec yet?

3 Gigabytes per second? Who told you that USB 3.0 would do 3 Gigabytes per second? The spec max's out at 5 gigabits per second. However, unless you are running an SSD drive, you are never going to come anywhere near that speed. I think most USB 3 devices tend to run 60-80MB/sec at present time from what I have read.

sygnus21 - I'm using the same ones and I still can't get out of the hole. Any suggesitons?

Unfortunately I don't have any suggestions as I said I'm not using mines. Actually what you should do is look through your user manual to see if there are any special requirements for using them.

I will hook up my external drives tomorrow and give you a screen shot of those.

I believe he meant 3Gb/s. i.e. SATA HDD speeds.

Or 6gb/s for Sata III drives. Using a USB 3.0 bus with a Sata II drive inside the external casing or enclosure will play a role in limiting speeds. A Sata III or SSD would expect to see faster access times. The make and model(s) of the drive would be a help with a look at the specs as well as support info.

Using a WD Passport Essential USB2-3 I get a around 40mbs at the USB3 port and 20mbs at the USB2 port. Transferring a 14GB folder consisting of various types of files takes about 6:20 min at USB3 and 13:30 at USB2. I also checked on a 2nd PC and the transfer rate on it was also around 20mbs at USB2 (no USB3 on that PC). Obviously, my USB3 is about twice as fast as my USB2 connection; however, I've know idea if these speeds are what to expect out of USB3.

Tranferring the same file from the external back to the internal is much faster at 60mbs. This lead me to believe that my limiting factor is the speed on my external drive (5200) and not the USB3 port. Perhaps your laptop's internal drive is 5200 or has another issue slowing it down - such as being nearly full?

Maybe a SATA III SSD, depending on the model, but not a SATA III o SATA II HDD. A HDD is not limited by SATA II.

I don't understand the whole discussion. Whether you have USB1, 2, 3 , or 99, the channel (attachment) cannot transmit the data any faster than the disk feeds it. USB3 is a LOT faster than any spinning disk around. You have to check the specs of the disk to get the story. And also be sure you always talk in the same currency - Mb/sec versus MB/sec - that is appr. 1:10.

I believe they already have some USB 3.0 devices released. With that, the speeds should be faster than what the OP is getting. That's his point.

I think we're losing sight of his issue.

Again, the OP needs to check his drivers, and check the owner's manual for the board.

My two cents.
