Fastest way to transfer large amounts of data to a NAS

I just bought a synology 918+, and I have about 16tb spread over a few drives currently set up in a JBOD enclosure that I need to transfer over to the NAS.

Should I just create the NAS share and drag and drop folders/files to transfer over the network, or is it better to remove each individual drive and plug it into the NAS USB3 or esata port and transfer the data through that direct connection?

Also, is there some sort of program that will monitor the transfer of data, to check that the files made it successfully, and if there are errors a program that won’t make me start the transfer from the very beginning again? Does that make sense?

Oh, and I’m sure there are a lot of variables that affect the transfer rate speed, but I’m curious if anyone knows what kind of speeds I might expect using the methods above.

Don't do that.

I would use RichCopy. It is multithreaded. Allow it the copy between 10-20 copies at a time and let her rip.

Huh, never heard of rich copy. I was going to suggest robocopy or emcopy if he could get a copy of it. I've been copying a few hundred tb over the last few weeks so I may have to look into that.

Ok so youre recommending to just transfer the files over the network then. The speeds will be about the same as a direct usb/esata connection?

Yes, because you are going to be constrained by the speed of the drives. Expect around 150MBs.

Synology does have an app that will auto copy anything connected to USB. I did something similar when I set up my 1019+. Just dump everything in a common folder, then parse out. Not ideal but it worked for me.

Thank you that’s good to know, and Thanks all for the feedback.


However I might have to remove each drive and transfer individually, because the current enclosure I’m using seems to be messing up and overheating. This is the main reason why I’m transferring to a NAS at this time. I don’t trust it anymore to stay on for long periods of time.

But I do have a usb 3/esata HDD dock somewhere in my house so it shouldn’t really be a problem, and it sounds like I could choose either network, usb3, or esata and they should al transfer at basically the same speed since you’re saying the bottleneck will be the actual HDDs themselves, which top out around 150mbs, well below the capability of the gigabit network, usb 3 speed & east speed.

I use multi-Commander to do all my large file transfers.

It is pretty powerful and had an easy interface.
