After posting in my HDD thread about how many partitions I can have with the maximum letter drives, I've decided to change my setup concerning my computer HDDs. I am now going though and deleting partitions and remerging them to make them back to one drive.

I have 3 external HDDs currently, one 3Tb, and two 5Tbs. Between the 3 HDDs I had partitions many of them, What I'm doing now is currently moving all the files I had on the drives to other drives so that I can merge the partitions on their respective drives.

My question is, Is there a way to move files faster from one drive to another drive? Granted I know that I am moving a crazy amount of GBs between drives but I think that like 22.4MBs is kinda slow. Unless this is normal for USB 3.0, All my external drives are USB 3.0 and my Mobo has USB 3.0 ports and all 3 of my externals are connected to their 3.0 ports.

Whats the normal speed of a USB 3.0 if what I currently have is not normal?

Is there a program that moves files faster between drives besides the Windows 7 stock file mover?

I was unsure that my externals were connected using "superspeed" but I downloaded USB Device Tree to check the connection on all 3 externals and in the connection info it does say "superspeed"

The time keeps changing from 6 hours for one window to 17 hours on the second window to be completed. I've already been though 6 hours, I started this at 3 Pm CST.

Something does sound wrong. I recently copied 4TB of content from one external HDD to another and was getting speeds above 100 MB/s (roughly 140 MB/s if I recall correctly) using Win10's stock file copying (just drag and drop) when both drives were on USB 3.0. I initially made the mistake of plugging one into USB 2.0 and my transfer speed was about ~30MB/s then.

I just benchmarked a drive on 3.0 with HD Tune and I see min/max/avg of 150.7/182.7/170.0 MB/s. I certainly didn't achieve that with real world copying of files.

You could try see if you get different results with TeraCopy, which I think is free but I've never tried, or some other tips here: http://www.makeuseof.com/tag/4-ways-to-copy-files-faster-in-windows/

If you're copying a LOT of small files, then speeds could be quite low (like 10-30Mb/s) due to the overhead, but if you're copying big continguous files and the speed is just 20+ Mb/s, then something is obviously wrong.

Older USB 3.0 external drives (eg. 500Gb USB 3.0 portable drive of a few years ago), may have top speeds of around 50-100Mb/s. But any recent 2Tb (and bigger) external USB 3.0 drives should easily have around 120-180 Mb/s top speeds (or higher) -- of course this is for transferring a contiguous big file stream. Since copying lots of small files would entail random accessing of the disk surface, which can make copying much slower.

This article is pretty oudated. I recently copied some gigs of movies on my acer travelmate 645, 256GB m2 sata from an SSD 6.0Gbps over a cheap chinese Sata-usb 3.0 converter. The max speed i could get was around 245MB/s and the average was around 220 MBps. I can share snapshots and more details if you like.
