WD 1TB Caviar Green Hard Drive @ Hot Hardware
“Western Digital recently began to ship a new series of Caviar hard drives that included the company’s Advanced Format technology. The new Caviar Green models are nearly identical to their standard brethren, but offer double the cache (64MB instead of 32MB at 1-2TB) and have a different model number. A WD10EARS is an Advanced Format drive; a WD10-EADS is a ‘normal’ drive.”
