NAS326 setup slow copy speed from USB

blackmambahk

Just bought the NAS326 and installed a single 3TB drive and currently I am trying to copy in data from a 3TB drive that I previously had as an external USB NTFS drive on a Windows 10 PC.

Once this is done I will then add the older drive into the NAS.

So I plugged the drive in to the NAS USB port, an initial test copy from the file browser showed it worked but was slow and now I am copying the whole drive via the copy button it is running at a little bit less than 1TB per day and I am about 1 day in.

This seem really slow to me, is there a quicker way to get all the data from drive into the NAS with this setup

TIA

1TB/day, is that 1TB/12h or 1TB/24h? In the latter case it's about 12MB/sec, so the first case is 24MB/sec. 24MB/sec is about the maximum you can expect from an USB2 disk.
Is it an USB2 disk?

NTFS is not the fastest filesystem for Linux. If you are copying a lot of small files, this can have a big impact.
Generally spoken, when you have to copy a lot of data from an NTFS usb disk, the fastest way to copy is connecting the disk to a PC, and copy the files over network. (Assuming you have a cabled 1Gbit network.
The most convenient way is the way you are doing it, but you should not be in a hurry.

1TB in 24h - The external drive is USB3.0 which is why I thought it was slow, also using the correct cable as the case uses a Type B connector.

Guess will just have to wait another couple of days for it to finish

Thanks anyway

One and a half days and reached half way!!
One thing I have noticed is that the CPU is just pegged at 100% for the whole time not sure why copying files should be CPU intensive and I guess this is what is limiting the speed.
So far it seems you get what you pay for with this NAS.

What process is using the CPU? It could be that it's generating thumbnails, or something like that.

cp 16.67
python 8.33
kworker/u2:2 9.09
python 8.33 (its in the list twice)

nothing else in the list but UI shows 100% in chart and desktop
I had disabled the Twonky Server for now and loaded the file to a new share hopefully to avoid any internal processing until later
