Western Digital Updates Green Lineup to 2TB

From DailyTech: Western Digital has announced its latest drive, a 2 Terabyte Caviar Green hard drive with 32 MB of cache and a seek time of 8.9ms. It runs between 7200 or 5400 RPM depending on load, which saves power.

Due to advances in Perpendicular Magnetic Recording (PMR), it is able to achieve this using a four platter design, with 500 MB per platter. Having fewer platters reduces power consumption as well.

WDC's precious capacity champion was only 1TB, so this new flagship has been anticipated for use in DVRs and archival systems. The model number is WD20EADS, and is being shipped to distributors this week.

In addition to the 2TB model, Western Digital is also launching a 1.5TB model (WD15EADS) to accompany its revised 1TB model (WD10EADS). Both also feature 32MB of cache, which helps to increase access speed to commonly accessed data.

"While some in the industry wondered if the end consumer would buy a 1 TB drive, already some 10 percent of 3.5-inch hard drive sales are at the 1 TB level or higher, serving demand from video applications and expanding consumer media libraries," said Mark Geenen, President of Trend Focus.
