I know these are very popular with data hoarders as they shuck the drives for their server.
it's a great deal, haven't had any experience myself, would be great to have this in a mirror
its roughly NZD 269.14 incl shipping for one unit
for 2 units is NZD 646.51 which includes customs fee of NZD 115.97 :(
