Copying files from external drive
Hi,
I have a Thunderbolt external hard drive with a usb3 connection. Connected the drive to my Personal readynas a little while ago to copy a lot of mp3 files over to the nas drive but it was painfully slow in fact it was just as quick to copy the files via wi-fi. I tried both usb connections on the nas drive and i know one of which i believe is usb3. So my question is this, Should it be faster copying direct or are there limitations. I am asking this question as i need to transfer about 60gb of mp4 movies over shortly and rather than disconnect my drive from the Mac and connect to the nas drive in the living room should i just copy over wi-fi?.

Part of the answer is that even if the USB drive is connected to the NAS you might actually be copying the data over wifi. For instance, if you do a drag-and-drop from finder, the data is read by the NAS from the external drive, transfered to the mac over wifi, transfered back from the mac again over wifi, and then written to the NAS to the internal array.
To avoid the network copy altogether, you need to use the built in backup job in the NAS to do the copying. Otherwise, as CPU8088 says, you should connect the mac to your network with ethernet, and attach the USB drive to the mac. That copies over the network only once, and ethernet is faster and more reliable than most wifi links.
How fast the various ways copying are depends on what ReadyNAS model you have and what firmware it is running. Can you provide that information?
