Hitachi Deskstar 7K1000.B  (Source: Hitachi)
Second generation 1TB drive uses 43% less power than the original

Hitachi was first out of the gates with a 1TB HDD and the other major hard drive makers -- Seagate and Samsung -- had to play catch up. Hitachi announced its second generating 1TB HDD this week that promises to be the most energy efficient 1TB 7,200 RPM hard drive in the world.

The drive is known as the Deskstar 7K1000.B and the main feature is the use of three platters that each store 374GB of data. With the drive only needing three platters, the idle power consumption of the drive is reduced up to 43% over Hitachi’s first generation 1TB HDD. The 7K1000.B also offers users the option of bulk data encryption (BDE) for the entire contents of the drive.

The 7K1000.B makes use of perpendicular magnetic recording and the drive’s BDE option uses AES encryption certified by the National Institute of Standards and Technology to deliver the strongest commercially available levels of security for data.

Power requirement for the 7K1000.B is 5.2W at idle and the drive uses a 16MB cache. The drive has a maximum media transfer rate of 1388 Mbits/s.  The Hitachi 7K1000.B will ship worldwide in July at an undisclosed price.

For enterprise users needing a high mean time between failure (MTBF), a DeskstarE7K1000 drive is also being introduced that has up to a 32MB buffer and a 1.2 million hour MTBF featuring the same low power requirements and optional encryption technology.

The first generation Hitachi 1TB HDD was released in January 2007.

How will it compare to the old one?

The 7K1000's good desktop performance was because of its low random access time, which in turn was a result of the five platter design. How will this new one make up for the loss of two platters?

Short answer: it won't. :D

Seriously, random access times can also be improved by better (ie, faster and more accurate) step motors, and by lowering total platter surface (aside from increasing rotational speed, which, in this case, we are 100% sure they didn't).
But if they could get slightly smaller platters AND increase the areal density at the same time, while also improving the motors and not making the drive more expensive... Then I'd say that I'm gonna buy a hat, just to take it off for the engineers at Hitachi.
