But, you ought to include the 440V, 1HP motor that spun disks, the head-of-string controller, and the 32"x44"x70" cabinet if you want to compare it to the WD 2TB drive. You could probably deduct the weight of the DC power supply, but you'd still be close to the 500 lb number that Tyler quotes.

That's real, formatted capacity in base-2. A rack weighs 1200 pounds or so. Therefore, random-access, usable space including CPU, network, controllers, power and air-moving is 1.2 imperial tons for us to store 1PiB. Shameless plug time (I'm tech-ops, not marketing btw). We recently made up some nice graphics describing how large a petabyte is. Blog link: http://mozy.com/blog/misc/how-much-is-a-petabyte/ At Mozy our latest racks store about 500TiB of data per rack.

The capacity is used in base 2 units of 10 bocks. That makes a 2^10 to change to next. You need 1024 GB to get a TB and you need 1024 Tb to get a PB. With what you used, you need 1024 / 2 = 512 disks to get 1 PB on 2 GB disks. And you need 1024 * 1024 = 1048576 disks to get a PB from 1 GB disks. I know aren't rounded numbers but when you put an scale you must use real numbers if you can although it gives you extrange numbers Anyone has notified that 500 disks of 2 TB are 1000 TB not 1024.
