Pros: Extremely reliable, extremely fast - I also have a Drobo which is a little spotty - also even with Thunderbolt the Drobo lags way behind on speed -

Cons: Like most RAIDs it is fairly pricey, but offers the security of knowing my videos and files are safe. I have had a drive go out on my older R6, and had to get help on the phone. They answered right away! Bought the new drive and was up and running in no time.

Overall Review: Very satisfied with my Promise R6 RAIDs. I have 2 of them and would definitely buy more in the future.
