I"m gonna echo a few things here after my current experience with the Drobo v2.
The USB disconnection issue is unacceptable. I have no idea why switching to Firewire fixed it for now, but this is the kind of thing you cannot have in a fault tolerant environment.
The rebuild times for 500GB on 1.5TBx4 to 2TBx4 border on unacceptable. Being forced to endure a days long layout is a real recipe for disaster. At the very least the dashboard needs to show me some sort of fixed progress about what it is actually doing (aka x of y bytes processed) rather than some wildly inaccurate time estimate. That way I can tell whether it is actually doing what it is supposed to be doing.
The dashboard software itself is weird … i don’t understand the need for two windows. It should just be the one window with 3 tabs. Not fatal, but really unnecessary.
The lack of self diagnostic information is not good in a product like this. The UI says nothing about the logs being encrypted, and it is not logical for a user to think a diagnostic run would not show him the diagnostics!!! Add a message saying the logs are encrypted for technical support, or better yet, actually show us the data we’re allowed to see! Drive health indicators are extremely important in a product like this.
That’s all for now.
