WD15EADS 1.5TB HDD
« on: December 06, 2009, 12:36:39 PM »

Anyone have this HDD in their DNS?
I have the newest firmware (1.03)

When ever transferring files (mostly ~4GB) using an ftp client the transfer will stutter/freeze for a second or 2 then continue with a drop in the transfer rate.

For example, it will start transfer at 10MB/s and continue for a minute, but then the transfer freezes/stutters for 2 seconds and starts again but the transfer drops a few MB/s. It will then begin to stutter every 3-5 seconds reducing the transfer rate each time until it gets to 2MB/s while it still continues to stutter. I have tried the dns on different networks (which had different PC's/switches/routers) and still experiencing the same problem.

Any ideas? is it maybe that this HDD is just not compatible?

I should also mention that when I try to access the dns through a mapped network drive sometimes it takes a while to respond (this is after some use so the drives are not in hibernation). Even when going through different directories it may take like 20-30 seconds after trying to open the directory that it will open.

Have you tried re-creating this problem with a different drive, just to ensure that it is not the 321 that is giving you the problem? If you have and it works fine, then I'd suggest that it is your drive will probably be the problem. And if you haven't then I would say to please try that, it's a good way to isolate the problem to one piece of hardware.

I haven't tried it with that particular drive, I don't own one myself. But I will be installing a set of them this coming weekend for a customer (RAID 1), I can report back here after that if you haven't already found someone that can tell you your answer.
