Storage company Western Digital has expanded its Caviar Green 3.5-inch SATA hard drive family with a new 2TB drive for USB/FireWire/eSATA external hard drives, desktop computers, workstations, and desktop RAID environments.

The company said the WD Caviar Green hard drive is based on its 500 GB/platter technology (with 400 Gb/in2 areal density) with 32 MB cache. Other features include: StableTrac to reduce system-induced vibration and stabilize platters; IntelliPower to fine-tune spin speed, transfer rate, and caching algorithms; IntelliSeek to calculate optimum seek speeds to lower power consumption, noise, and vibration; and NoTouch ramp load technology for better drive protection.

Last year the company released 3.5-inch 1TB SATA drives under its WD Caviar line for desktop, workstation, and multi-drive systems.

Jim Morris, senior vice president and general manager of client systems at Western Digital, said: Saving power without sacrificing storage capacity is what consumers want. With the launch of the new WD Caviar Green 2 TB hard drive, customers receive the additional capacities needed to operate today’s highly advanced programs and high-resolution digital files while using less power than typical drives with similar performance and capacities.
