I was able to ship 5 of them to my neighbor and the order went through. Just in time too because they are sold out!
I hear you on the 2TB size. I look at it this way, I bought a SA120 for $150 brand new and can daisy chain it to my existing SA120. So being able to pick up a really nice HDD for $40 and fill a $150 enclosure seems reasonable. Now if I had a super high end enclosure or server, right, no wasting the space.
Normally I would also worry about the power draw per GB as well since 12 spinning 2Tb drives cost a lot more in energy than 3 8TB drives! But since I only plan to turn this thing on twice a month for less than a day, it shouldn't be too big of a deal!
