Picked up the 6TB version to be used out on set during production. We've had this out on 2 shoots so far and it is working as advertised, which is all you can ask for. It is a large drive, think a little smaller than a GDrive. It is externally powered. It is quiet, as it is currently offloading 5TB of footage right next to me now. Transfer speeds are as advertised. I do really like their 3-2-1 warranty, we retire most drives after a year, and knowing during that year they will overnight a new drive if we need it is great. We have been looking for a replacement for the GDrive and Lacie family and I believe we have found it. We will be picking up more and will be trying out their other products.I'll update this review periodically as we put this drive through its paces.
