I'm not sure if this is a Mac issue or not and if it is, maybe it's just a problem with Yosemite.I don't really know when it started as I may have been copying smaller files without really noticing a change in speed but in the last few weeks I have noticed a significant drop in copying speed from my ReadyNAS Duo (v1) to my MacBook Pro I am currently copying a folder with 5.24 GB of data and Finder says it will take 48 minutes. Not so long ago, it would have taken about ten minutes.I have rebooted everything several times, Mac, Router (Netgear DGND3300 v2) and the ReadyNAS Duo. I'm pretty certain that it is neither the Mac's write speed or the router's transfer rate as performance in other areas has not changed.It could have started when I updated to OS X 10.10/10.10.1.I'd be very grateful for any advice.

What firmware is running on the duo?How full is the volume on the nas?Have you tried a direct connection with the mac?

4.1.13 - i know there is a newer version which I have downloaded but I have been waiting for a window to install it.Less than half full - <1TB/2TB.That's pretty problematic but I may be able to try it in the next day or so.I should also have mentioned that connecting also seems much slower.

I'd check the disk health also.Do you have ssh installed?

I have now installed Frontview 4.1.14I looked at the health - all is reported as OK.I remember walking through a process with somebody once which involved using SSH but that was at least a couple of years ago and I don't remember how I went about it.[edit] No noticeable difference after firmware update:720MB by AFP - 6m720MB by CIFS - 7m

One thing you can check is the fullness of the OS partition.Ssh in and df -hdf -iPost the results. Doesn't sound like this is the problem though.Are you referring to the problem you had with DLNA?

Ssh in and
df -h
df -i

Post the results. Doesn't sound like this is the problem though.

I don't remember what the problem was but it's quite possible.

If you are the person who helped me, I haven't touched SSH since then and I am afraid I have slept about 700 times since so any recollection of SSH and how to access it has evaporated, I'm afraid.

Incidentally, this is what Health says:

Device Description Status
Disk 1 Seagate ST2000DL003-9VT166 1862 GB , 26 C / 78 F , Write-cache ON OK
Disk 2 WDC WD20EARX-00PASB0 1862 GB , 25 C / 77 F , Write-cache ON OK
Fan 1 1595 RPM OK
UPS 1 APC Back-UPS ES 700G, Battery charge: 100%, 31 minutes OK

The reason I have different disks is that I had a failure and Netgear replaced one under warranty but didn't have the same brand, Seagate. It was either wait indefinitely - they said it could be months or maybe never - or accept the Western Digital disk.

WiFi - but it always has been. Nothing has changed in terms of the physical system prior to or since the transfer speed dropped.

It wasn't me, it was, unusually, mdgm.
To ssh in you need to install something like putty on your pc, run it and enter the ip address of the nas.

The login is root
The password is the same as your admin password.

edit: of course, you have a mac - see StephenB's post below

You must first check a direct connection to rule out a network issue
