Windows 7: USB Speed Issues?

USB Speed Issues?

I just did 490 GB worth of file transfers (move) from one USB 3.0 external drive to another USB 3.0 external drive. Ill call the source drive A, the other B.

Im using TeraCopy for the first time (and Im impressed so far for speed and ease of use). Total time was 40-45 minutes (I didnt look at the clock right away) and seemed to average of 150-155 MB/s (the progress bar would dip into the 140s and peak in the 170s).

I was impressed.

Now that drive A has the needed room to put the files I want on it, I disconnected drive B and began to Copy files from an internal HDD (WD Black) to drive A.


Its been running for 1-1/2 hours now and has only 350 GB (out of almost 1 TB) of files copied over!? The progress bar was showing only high 60s MB/s for the long time but bounces into the 70s from time to time. And hours to go still

It was taking so long that early on I stopped the process and moved drive A from the back plate USB type A socket to the front panel USB 3.0: no difference in speed.

Kudos to TeraCopy for remembering the destination folder even after being closed down and after the drive was in another port.

So any ideas of whats going on? The only thing I can think of is drive A has good read speeds but terrible write speeds.

Thank for the info and link. I havent had much time to play with it. I did plug in the original source drive A and it is set to Quick Removal. When I plugged in the original destination drive B I expected it to be set to Performance since transfer speeds to it were great; it wasnt, it was also set to Quick Removal.

The only thing Ive had time to test out is simulate the internal HDD file copy to drive B and see if it went any faster than copy to A, and it did. I copied 126 GB of files from HDD to B and it took about 23 minutes. Not quite as fast as A to B but a lot faster.

Makes me wonder if drive A is a 5400 RPM drive and B is a 7200 RPM unit.

Ill have to wait for time to play with it more
