Staggered, or delayed, spin-up enables the host to individually “spin-up” drives in multi-drive configurations. This reduces the power draw of a booting system, enabling system designers to reduce the size of the power supply and minimize the total cost of ownership for end-users.The three drives also feature Hitachi's "Smooth Stream" technology which is said to optimize video streaming by allowing the host to control the hard drive's error recovery process and thereby enable the drive to better capture video streams.
The two miniature drives are noteworthy, too. "Mikey," the baby Microdrive, is a one-inch hard drive with capacities from 8 to 10 GB. "Slim" is being billed as the world's smallest and lightest 1.8" hard drive. The newest Travelstar will come in one- and two-disk versions with capacities from 30 - 40 GB and 60 - 80 GB of storage, respectively. These drives are tailor-made for future digital music players.
