Windows 10: Copying to external Hdd very slow

There is an option to use Macrium (free) to do a folder/file backup. It's reliable and fast. And can be picked at simply by mounting the image created. Just a thought....

 

Hi there.

Macrium is good for IMAGING HDD's (usually the OS) but probably not a good idea for copying DATA -- problem is once you've copied the data with Macrium you then have to restore it again !!!. No problem for OS partition - but if you are copying say 4TB of multi-media data that's going to take a LONG time to back it up and restore again --this is one area where a simple copy works best.

USB3 should work -- I can get native speeds of up to 220 Mib/S - average as I showed before around 110 Mib/s from an external USB HDD (passport self powered type).

I can only surmise that the bus speed of the Mobo in the computer isn't fast enough or the drivers aren't correct. Usually USB3 is decently fast even for copying a few TB of data.

Hi Luc.

Will you allow me to see your system in a bit more depth? I want to check two/three things actually. Can you please upload your MSINFO32.nfo file?

Yes, Jimbo... moving 4TB of data from A > B using anything is going to take a long time. BUT, you do not have to restore the entire data backup I described to get to 1 file. Mount the image and copy the file.

 

Hi,
I uploaded my systeminfo.
I hope you can read it because it's in dutch...

Bye,

Hi,

That SyncToy app is just great !
I tested it for keeping my files on the 3tb-disk updated and it works 100% !
Very nice program !
Thanks for that tip !

Good to hear! Please make sure you are familiar with the three options for use, they function differently. There is an excellent tutorial on our sister site Sevenforums for this tool. It will explain in depth the inner workings. Enjoy! TC

Hi,

I just went to see the tutorial and it conferms what i found myself.
I created 2 folders and put some files into the "left" one.
Then i fooled around with changing, renaming and deleting files in both locations.
Found that the "contribute" option is the best for my needs.
So thanks again...
I'm a happy man ;-)

Great! Anything else, just post. TC

 

Hi Luc. I see that you have got a solution. If you are interested, I am posting what I have found in that file.

This happened 37 times.

A clean startup is recommended.
Also, it seems that the Intel USB3 device is using the microsoft suggested driver.
Code: Intel(R) USB 3.0 eXtensible Host Controller - 1.0 (Microsoft) PCI\VEN_8086&DEV_8CB1&SUBSYS_85341043&REV_00\3&11583659&0&A0[/quote] If ASUS has any feasible USB3 driver in their website for your computer/motheroard, try that one, too.
The items stated in Point 4 and its subpoints are also to be considered. Common issues in USB 3.0 devices | Microsoft Windows USB Core Team Blog

 

Hi,

Why?
Besides the obvious problem OP has with the USB port there's also the fact that he's copying loads of small files.
That means opening files, writing it to destination, closing it and verifying the lot x times.
IOW, that's going to take more time than Macrium imaging the drive's data and putting it onto the destination drive because it can take priority over running processes whereas Windows does not unless you tweak it.
That, plus it is now acting as a single file source which means much les processing time. That's why it can work so fast.

Other factors to consider are the HDDs are slow, much slower than USB 3.0 or higher transfer rates allow for.
If, on top of that, you connect a SATA II drive to an USB 3.0 port you will notice the drive choke on the transfer and W10 will fall back to USB 2.0 or lower.

Either way, the problem certainly doesn't lay with Macrium's , it's agnostic of whether it's copying an OS or files or whatever.
