Re: Best Hard Drive Availability in the Market

My Review on Western Digital 500GB SATAII:
  • Western Digital's line of Caviar GP have been considered by many as a value-graded hard drive because of it's completely affordable and cheap as compared to other hard drive company.
  • The Western Digital Caviar GP is actually designed for lower power consumption. Hence, the moniker GreenPower or GP. Western Digital claims these hard drives use 4-5 W less power than its competitors.
  • A 500 GB model was tested by a harware testing company and they were most impressed with its performance. It provided a large storage capacity using only two platters, it also delivered very good performance numbers. The noticing feature is it had the same platter-to-buffer transfer rates as the more expensive enterprise-grade.

Re: Best Hard Drive Availability in the Market

Have a Look on This:

Western Digital 500 GB Hard Drive

This Western Digital Caviar hard drive is part of their GreenPower series, hence the GP label. Viewing through Western Digital, the Caviar GP hard drives offer an average power saving of 4-5 watts over their competitors, a feat that they claim is equivalent to reducing CO2 emissions by 13.8 kg per year.

Western Digital has three different Caviar GP models with capacities of 500 GB, 750 GB and 1 TB. The model to be discussed here is the 500 GB model which uses two platters. The other two larger drives use 3 and 4 platters respectively.

Caviar GP hard drives support the following features :

IntelliPower - A fine-tuned balance of spin speed, transfer rate, and caching algorithms designed to deliver both significant power savings and solid performance. For each GreenPower drive model, WD may use a different, invariable RPM.

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

IntelliPark - Delivers lower power consumption by automatically unloading the heads during idle to reduce aerodynamic drag.

Preemptive Wear Leveling (PWL) - Proactively monitors and prevents magnetic wear during high read/write duty cycle applications.


StableTrac - Secures the motor shaft at both ends to reduce system-induced vibration and stabilize platters for accurate tracking, during read and write operations
