There is nothing but awesomeness and performance out of this G-Raid. I have it sitting right behind my dual Thunderbolt Displays and I can't here but a whisper. As an avid audiophile who slices his wrist if I can hear a single little tiny hizz, buzz, or fan, even though all my other HDs are SSD I can barely barely hear the G-Raid two foot from my nose. Just transferred 4 gigabytes from an external SSD to the G-Raid 8TB... it took 6 seconds. Awesome product, and knowing I'm dealing with Enterprise quality HDs, forget about it.
