I just bought the ReadyNas 204 and installed in it 2 WD RED hard drives of 2TB each.
This HD model is compatible with the readyNas 204.
I installed and updated the OS to version 6.4.
So far so good. I have no prior experience with NAS technology, so I was baffled when I realized that the transfer speed to my disk was extremely slow. I did some checking with different configurations, but the bottom line is it takes about 4.5 minutes to copy an application file of 630 MB. It's an application package, so it includes both large and small files.
I used two different router (an Apple Aiport and and Fritzbox), and also tried with an ethernet cable and wireless. I also used and old mac mini in addition to my Macbook Air. The Macmini is even slower, the Macbook air with an SSD and El Capital is actually quite fast.
Since I wasn't getting me anywhere I thought maybe my HDs were somehow defective or slow, so I took one out and put it into a USB enclosure. It takes the Macbook air 20 seconds to copy the same file to the disk.
I also tried to delete the copied file from the NAS. It took the NAS literally for ever to do so, when it worked at all. In some it displayed in obscure error message "The operation cannot be completed because the item 'frameworks' is in use.
So - I would be very grateful if some one could explain to me how to get a decent speed out of this system.
