Thanks for the response davo. That's not really what the question is about though. I 'know' that the system will accept 4x500GB drives for a total of 2TB of storage. What I'm wondering, even though it isn't officially supported by Buffalo, is whether or not the system will accept 4x1TB drives for a total capacity of 4TB (3TB in raid 5). Is there a limitation in the bios/kernal/raid controller?
I do understand the upgrade process you're talking about, and that's how the drives will eventually get loaded, but the question is about drive size.
Thanks for the bump though ;)
