Duel 2TB Seagate Barracuda LP vs. Western Caviar Green

Duel 2TB Seagate Barracuda LP vs. Western Caviar Green
In early 2007, Hitachi was the first to launch a hard disk with a capacity of 1 terabyte, the 7K1000. At the time, this integrated disc 5 trays of 200 GB each, all running at 7200 rpm. Since, perpendicular recording to making progress so as Seagate Western arrive on the market with 2 TB drives! 

To reach this capability, manufacturers opt for an architecture with 4 trays of 500 GB each. Western was the first to announce such a drive, the Caviar Green WD20EADS. Launched in January 2009, it has long been undisputed record holder in its class. Did not count on that Seagate launched in April a new line, the Barracuda LP, reaching the same capacity.

5900 rpm vs IntelliPower

Only problem, Western continues to do mas communicate the speed of his trays: If you could understand the rigor in the beginning, now that other manufacturers have followed one wonders why keep such a secret. Therefore, we only know that the Caviar Green have "technology" IntelliPower, which I quote "A fine-tuned balance of spin speed, transfer rate and caching algorithms designed to deliver both significant savings energy and solid performance. "In practice, the speed is around 5400 rpm. 

Conversely Seagate unambiguously communicates the rotational speed of the Barracuda LP: 5900 rpm. This speed is rather original compared to the usual 5400 and 7200 rpm, but why not.

Perfect for some uses
The 5400/5900 rpm disks are interesting choice for many types of uses. The first course for a machine that does not require phenomenal performance but a large storage capacity and good environmental characteristics, such as a home theater PC. But they will also be very well their office in a NAS.
