I love how fast it is and quiet. It works very nicely! The only complain I have: the description states it is 8TB (4drives 2TB each), but actually one of the drives is already sacrificed for the RAID management which takes about 2TB, so you only have 6TB left to work with. I was dissapointed about this mis-understanding. They said you can erase the Raid system and get all 8TB available, but hey, that's why we pay such high price in the first place: to get it all secured with this RAID system - so of course you keep it there. That way, even if your 1 drive goes bad - you don't really lose any data... Overall, I am currently still very happy with how it performs.
