I just did 490 GB worth of file transfers (move) from one USB 3.0 external drive to another USB 3.0 external drive. I’ll call the source drive ‘A’, the other ‘B’.
I’m using TeraCopy for the first time (and I’m impressed so far for speed and ease of use). Total time was 40-45 minutes (I didn’t 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’.
Gasp…
It’s 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 what’s going on? The only thing I can think of is drive ‘A’ has good read speeds but terrible write speeds.
