been using this for 3 months now first of all you get only 45tb space out of 5tb remember that second thing is the copying speed entirely depends on your processor and ram this thing can copy at max 120mbs in my 8gb ram i7 processor laptop but copies at max 6070mbs in my another 2gb ram i3 processor laptop build quality is trash protect it like a baby even small drops could damage entire frameplastic must buy a case as for protection you can use seagate toolkit for pass
