WD Caviar Green 2TB
As promised, Western Digital today launched the Caviar Green 2TB, the world's first desktop hard drive to cross the 2TB milestone. The 3.5-inch SATA drive takes advantage of the 500GB per platter technology behind its 1.5TB drive to reach the record capacity but uses intelligent seek patterns and on-the-fly changes to spin speed, reducing the amount of power used in certain loading situations or in low demand.
The drive carries the same 32MB of cache as its more recent counterparts and is designed to prevent the drive head from ever touching the magnetic surface itself and thus guarding the disk from easily wearing out or from breaking if the drive is moved. Western Digital is making the 2TB drive available today and says it officially sells for $299; no mention is made of price cuts to 1.5TB and below drives.
