I wanted to start out by saying, unbelievable, but then I realized that it is COMPLETELY believable. It was practically inevitable.

Then I said, "Actually it is unbelievable that it was inevitable...wait...that's a bit of weird logic."

Anyways. We now have available to us a standard 3.5 inch hard drive that has a 1 terabyte capacity. For the layman that is 1000⁴ = 10¹² or 1,000,000,000,000 bytes.

Here is the full review: Hitachi's Deskstar 7K1000 hard drive

Being first to the terabyte mark gives Hitachi bragging rights, and more importantly, the ability to offer single-drive storage capacity 33% greater than that of its competitors. Hitachi isn't banking on capacity alone, though. The 7K1000 is also outfitted with a whopping 32MB of cache—double what you get with other 3.5" hard drives. Couple that extra cache with 200GB platters that have the highest areal density of any drive on the market, and the 7K1000's performance could impress as much as its capacity.

Unbelievable. heh.
