Introduced on January 27 2009, the Western Digital Caviar Green WD20EADS is a 2TB internal desktop hard disk. Leapfrogging Seagate's 1.5TB model which has held the capacity record for 3 months, the 2TB WD20EADS is part of Western Digitals 'eco-friendly' Caviar Green line - meaning it uses less power than the standard 7200RPM drive. While this allows the drive to run cooler and quieter, it does have an overall negative effect on performance. Regardless, these drives massive capacities are ideal for long-term storage, for things such as media or backups - and thus this is what this line is intended for. It is also safe to bet that the higher platter density of the drive should improve overall performance next to the previous generations of Green drives. The drive is available immediately for the price of $299.
