DSM-G600, DNS-3xx and NSA-220 Hack Forum

Why do you feel it's the DNS-323 that's continuously interrupting the file transfer and not the Vista desktop?

You haven't given us much detail to work with.

The overall speed of a file transfer is only as fast as the slowest item in the channel - you have data going from a disk in the DNS-323, through a disk interface & a network interface in the DNS-323, across a network interface, through a network interface in the PC, probably through the processor, through the USB interface, through some sort of USB to ATA/SATA converter and then to the second disk.

File size also has an impact - 500 x 4 GB files will take longer than a single 2 GB file even though the actual quantity of data is the same - for each file the head/arm assembly in the destination disk has to move from the data area to the directory area and back.

Let's look at the "network hanging"

It would appear that you could have the DNS-323 powered up and apparently idle, until you switch on a particular PC, and then some sort of network activity starts - kind of sounds like something on the PC is accessing the NAS doesn't it?

I thing this is a problem with Windows Vista.. I don't have any issue with Windows XP Pro.

Thanks all for the replies.

I will measure this with other OSs. On the same PC I have Win XP and MacOSX (hackintosh) installed and I will try to understand if this also happens in those OSs.

The picture presented is related to a complete copy of the disks over network. I mainly have movie files, from 700k (more) to 4Gb (less).

I get much faster and smoother transfers writing to the DNS323.

This is also what happens to me.

I also have connected to this switch a MacMini. And this I am sure it happens with any of the OSs or any the 2 machines (PC/MacMini). Some times it even happens on its own, without being acessed at all. Other times happens after I turn one of the machines off.

You've completely missed the point - this is not about the OS - it's about WHICH device is causing the problem - the source, the network or the destination.

OK. I will try to measure this with other computers (MacMini for example) and try to change the switch. I will then have a more clear understanding of which device is causing this problem.
