It took the hard drive makers a while to exceed the maximum capacity of 160 GB at 5,400 RPM or 100 GB at a 7,200 RPM revolution speed. But ever since perpendicular magnetic recording (PMR) took off, there seem to be new capacity points and new speed records almost every other month, especially in the 2.5″ notebook hard drive segment. In this article we will summarize some news and look at three of the latest models. Samsung, Toshiba and Western Digital were the first to provide 320 GB notebook hard drives. However, Samsung’s Spinpoint M6 drive was the first product to reach our storage test lab; the other two drives will follow shortly as they become available. These drives represent the crème de la crème of the high capacity notebook hard drive segment, while 7,200 RPM drives max out at 200 GB capacity.

Those who wanted to ship their terabyte hard drives fast came in late this time. I’m referring to Samsung and Seagate, who intended to overtake Hitachi by providing terabyte hard drives based on a higher data densities, and thus using a smaller platter count than the Deskstar 7K1000’s five platters. Fewer platters per hard drive mean fewer mechanical parts that wear and tear, and the side effect is always better transfer performance. All of this remains theory, though, unless products are actually available. We still haven’t seen Samsung’s three-platter terabyte hard drive, but the Seagate Barracuda 7200.11 has finally arrived. While capacities seemed to be stuck at 500 GB for a while, with only Seagate going up to 750 GB, we now have three contestants battling at up to 1000 GB.

Hitachi Ltd. Sunday unveiled a new technology that it said can be used to cut the size of hard disk drive recording heads in half, which would dramatically boost storage capacity.
The company announced the new nanometer recording technology at the Perpendicular Magnetic Recording Conference in Tokyo.
John Best, chief technology officer of Hitachi’s global storage technologies unit, predicted that the new nanometer recording technology will eventually enable the disk drive manufacturer to expand the capacity of desktop disk drives to 4TB, and of notebook computer drives to 1TB.
Hitachi said the new technology will be used to build current-perpendicular-to-the-plane giant magnetoresistive (CPP-GMR) heads.
