Given all the stuff you've got squirreled away on your NAS, maybe you should be thinking of stepping up to RAID for a bit of storage insurance. Craig Ellison looked at D-Link's DNS-323 and liked what he saw.
I actually just ordered 2x Seagate 500 Gig SATA drives yesterday morning from Newegg... they were (still are) at $150 a piece, and $4 to ship each to me.... Any word on when this NAS will be available? Every page I have found shows it to be out of stock or backordered, including D-Link's page.
Also, as the previous poster stated, there is still no "join our discussion on this article" link within the article.
The D-Link DNS-323 is a terrible device. It was a waste of time and money for me. Dumps data just by powering it off & on. Tigerdirect will not refund me my money because it is a programming error on the unit. D-Link will not issue a refund because they don't refund people for their products and only tell you to contact the seller, Tigerdirect.
I could barely hear Tech Support and their phone system dumped me 2 times, both times the Tech Support tech was talking to me mid-sentence.

This device should not be used to back-up data!!!
