|Western Digital Caviar Green 2TB Hard Drive
Western Digital is one of the big names in hard drives, and one of their latest releases puts a much stronger emphasis on the word big. Model number WD20EADS is a 3.5" SATA 3Gbps hard drive that sports 32MB of cache memory and an industry leading 2TB of storage capacity.
Western Digital offers a range of hard drives with specialized features to make them more appealing to different applications. While some of their drives are intended for every day use, some are better suited to enterprise environments, while others were designed with high performance gaming systems in mind. The 2TB drive in question is from their Caviar Green line up, an "eco-friendly" series of drives intended to run cooler, quieter, and to use less power.
In this review we'll take a look at the typical performance characteristics of the Western Digital Caviar Green 2TB hard drive, but since it is touted as being eco-friendly, we'll focus on the heat generation and power consumption, too. Before taking a closer look at the drive provided for review, let's take a look at some published data taken from the official product page on the Western Digital website.
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.
Ideal For - Environmentally friendly PCs and external storage requiring lower power consumption and cool, quiet operation.
