WD, the world's leader in external storage solutions, today introduced its newly redesigned My Book World Edition network storage drive, simplifying the critical but tedious task of backing up an entire household's precious files. Designed for consumers who have multiple computers on a home network, the new drive will be available in 1 terabyte and 2 terabyte capacities, and is compatible with PC and Mac computers.

Seagate today introduced its Constellation family ofnew enterprise storage solutions for Tier 2 nearline storage applications. The two new drive models, the 2.5-inch Constellation and the 3.5-inch Constellation ES hard drives, include a combination of features that enable high capacities, increased power efficiency, enterprise-class reliability, and data security. Both drives also include PowerChoice from Seagate, which decreases power consumption by up to 54% for record power savings in enterprise environments.

"The need for greater storage capacity will continue to expand in multiple directions and dimensions, but there will be an increasing scrutiny of all storage system purchases, with an eye to decreasing power consumption, footprint, and cost per GB in unprecedented ways," said John Monroe, a research vice president at Gartner. "Performance will not be ignored, but a flexible balance of capacity, cost per GB, power and speed will become more crucial in fulfilling end-user storage demands at varied price points."

WD today announced the first 2 terabyte (TB) hard drive - the world's highest capacity drive and the latest addition to WD's popular, environmentally friendly, cool and quiet, WD Caviar Green hard drive family. This new 3.5-inch platform is based on WD's industry-leading 500 GB/platter technology (with 400 Gb/in2 areal density) with 32MB cache, producing drives with capacities of up to 2TB.

Western Digital (WD), seems to have matched rival Seagate's per-platter storage density mark, with its 500GB platter technology. What's more, WD is planning to release a quad-platter hard drive totaling two terabytes of unformatted capacity before Seagate could achieve that feat with its Barracuda 7200.12 series. Seagate was the first to come out with a 1.5TB hard drive with four 375GB platters.

The 2TB hard drive by WD (model: WD20EADS) lists under the company's Caviar Green series. It makes use of a 32 MB cache. Its access time is rated at 8.9ms, though its spindle speed is variable, between 5400 and 7200 rpm. The variable speed brings in power savings. It uses the standard SATA II interface. European online retailer Czech Computer started listing the drive, though its price isn't announced just as yet.
