Super slow copying to USB 3 external drive

Featured Replies

Hi again!

 

I'm in the process of moving heaps of stuff off my unRAID server. At the moment I'm trying to copy my tv shows from my media share to a USB 3 external drive. The issue is that occasionally I get good transfer speeds, but most of the time the speed is appalling! I just took a screenshot of my current transfer using Luckybackup.

I've tried Krusader and I have the same issue. I decided to try and stick it out with Luckybackup because I'd read that it uses rsync and that apparently using rsync helps. 

 

My guess is it's an issue with the actual external drive, but I thought I'd ask you all here anyways because I have a lot to transfer and this has already been going for over 12 hours.

 

In case it helps, I've attached my diagnostics zip which I downloaded immediately after I took the above screenshot. 

 

Thanks in advance!!

Seems you transfer those files in parallel, you should set it in one by one.

Hi, thanks for replying, but I don't quite understand.... It's that info somewhere in the diagnostics zip?

From your screenshot, we can see several transfers at ~26% and between 1.5MB to 500kB/s.

That's the slow progress of the same large file from what I can see.

That's correct.

 

Initially it was transferring close to 200MB, but I haven't seen that sort of speeds for a long time. 

 

Am I probably correct in assuming that the issue is with the actual external drive?

It does seem quite likely. Are you copying a really large amount of data, and is it an SMR drive?

I'm trying to copy over a little over 3.5TB of tv episodes. I don't know whether or not it is a SMR drive, but from everything I've read about SMR and CMR drives, is leading me to believe that it's highly likely that the drive is an SMR drive. 

 

The drive is a brand new drive that I bought for one of my kids. When I realized that I needed an external drive, I went looking in my son's bedroom for it, and found it completely out of it's box and in his old toy chest, so he probably didn't look after it all that well. I think I'm going to need to find another solution to this. Maybe I can sign up to a trial cloud storage....

You can try to cancel the transfer, wait a couple of hours (with the drive still plugged), then start it again. If it's fast again and then slows down again after a couple of hours the drive is probably OK, just the "joys" of SMR...

 

You can also click on the "Dev X" for it in UD, go to the Self-test tab, download the SMART report and post it here, that should give hints as to whether it has issues.

Thanks for your reply.

 

I managed to find a couple old internal drives, which I've installed. I am currently transferring data to one of them now, and I'm getting between 100 and 200 MB/s, so it's pretty clear to me that the issue was the drive. 

 

Thank you all again for your help. I have managed to solve so many questions due to the support I've read from this forum. Cheers!
