Western Digital Caviar Green 2TB HDD WD20EADS
It wasn't too long ago that technology pushed the 1TB limit on hard drives back and now Western Digital provides the same push to 2TB. The Caviar Green drive is certain aimed for high density storage.

Intro

Storage technologies have really pushed the limits of magnetic storage to the extreme. It wasn't too long ago that many "experts" said that storage built on magnet disks would reach their end of life due to not a blocked of bit density. All those barriers are still being shatters and new ones keep being made. While it is certainly true that mechanical parts are slower than their solid state successors (and SSDs are the true successor to the traditional HDD), at certain workloads, the magnetic storage can keep with with these new technologies by having very good linear read speeds. Combine that with a multitude of speed enhancing technologies and a big cache size, the hard drive has some life in it yet.

Did we mention that Western Digital arrived at the 2TB size? Their first consumer drive in that storage size is the Caviar Green WD20EADS 3.5" SATA HDD. Combining an green design that reduces power and noise, this drive is a good start to please the masses with its 2TB of storage and 32MB of cache.

Packaging

Since this drive arrived pretty much fresh off the line, it arrived in a generic OEM box. If you ordered a OEM drive, this would probably be the packaging it would come in.

Once opened, all that was contained is the drive proving this is an OEM drive fresh off the line. It was wrapped in an anti-static bag and protected well during transit.

Features

Quote

Reduced power consumption - WD has reduced power consumption by up to 40 percent compared to standard desktop drives with the combination of WD's IntelliSeek, NoTouch, and IntelliPower technologies.

Helps enable eco-friendly PCs - WD Caviar Green drives yield an average drive power savings of 4-5 watts over standard desktop drives making it possible for our energy-conscious customers to build systems with higher capacities and the right balance of system performance, ensured reliability, and energy conservation.

Cool and quiet - GreenPower technology yields lower operating temperatures for increased reliability and low acoustics for ultra-quiet PCs and external drives.

Massive capacity - Capacities up to 2 TB offer the most available capacity for storage-intensive programs and space-hungry operating systems, like Window Vista, with plenty of room left over for photos, music, and video.

Perfect for external drives - External drive manufacturers can eliminate the need for a fan in a high-capacity product with a WD Caviar Green drive, the coolest and quietest in its class.

IntelliPower - A fine-tuned balance of spin speed, transfer rate and caching algorithms designed to deliver both significant power savings and solid performance.

IntelliSeek - Calculates optimum seek speeds to lower power consumption, noise, and vibration.

NoTouch ramp load technology - The recording head never touches the disk media ensuring significantly less wear to the recording head and media as well as better drive protection in transit.

Perpendicular Magnetic Recording (PMR) - Employs PMR technology to achieve even greater areal density.

StableTrac - The motor shaft is secured at both ends to reduce system-induced vibration and stabilize platters for accurate tracking, during read and write operations. (2 TB models only)

Low power spin-up - WD Caviar Green drives consume less current during startup allowing lower peak loads.

Advanced power technology - Electronic components deliver best-in-class low power consumption for reduced power requirements and increased reliability.
