Bigger drives getting faster.

Looking for a consumer-level 2 TB 7,200 RPM hard disk drive? Hitachi is the first to the table to offer such a product. While Western Digital was the first to 2 TB and Seagate was the first to take it to 7,200 RPM with an enterprise drive, Hitachi's freshly announced 2 TB Deskstar 7K2000 is the first to in its size class for the mainstream desktop user.
The new Deskstar 7K2000 uses a five-platter design with "relaxed bit density" and perpendicular magnetic recording (PMR) technology. The drive also features a 32 MB cache and a 3 Gb/s SATA interface. Thanks to newer power management technology, the Deskstar 7K2000 offers 10 percent idle power savings over previous generations.
In addition to the new 2 TB Deskstar 7K2000, Hitachi announced that it is also refreshing its high-volume desktop hard drive family. The new 7200 RPM Deskstar 7K1000.C family will deliver up to 500 GB per platter, and will come in capacities of 160 GB to 1 TB.
Let's assume you get 8 hours sleep a night that's 1050 days or 2 years and 10 months of solid watching. You could watch all of Star Trek Next Generation, Deep Space 9 and Voyager for 45 times repeatedly.
Or you could just watch the Extended Lord Of The Rings trilogy about twice, and skip the end credits second time around...
Some people need these kinds of capacities...
