The new WD 1TB Scorpio Blue 2.5″ hard drives weigh 117 grams each.

1000 of them weigh 117kg, less than 1/3 of the 3.5″ 2TB drives!

At Mozy our latest racks store about 500TiB of data per rack. 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:

Anyone has notified that 500 disks of 2 TB are 1000 TB not 1024.

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

The question of disk drives vs memory cards is just arguing about the packaging.

Einstein showed that mass is equivalent to energy.

It has also been shown that information is equivalent to energy, so we should be able to directly convert 1PB of data to an equivalent mass and say what it should weigh without the packaging.

32 GB SDHC cards exist: http://www.newegg.com/Product/Product.aspx?Item=N82E16820208480
You’d need 32,768 of these to make a petabyte. These would weigh more than microSD cards, though. Probably more like 10g, so the weight would be comparable to the hard drives. Incidentally, I’m not convinced microSD cards only way 0.5 gram. I would’ve expected 2.0.
