For the past few years, Western Digital's consumer desktop hard drives have been divvied up into three distinct families for users with different needs. The Caviar Blacks provided high performance at a premium, Caviar Blues had balanced qualities for everyday use, and Caviar Greens delivered energy efficiency and low noise operation. The Green's qualities were mainly a result of a reduction in motor speed from the industry standard 7,200 RPM. But, what it lacked in speed, it made up for in price; more often than not, Greens offered the best capacity to price ratio, enabling budget-conscious consumers the luxury (or curse) of becoming digital hoarders.

The WD Red 3TB and 1TB.

The new Red series dumps the "Caviar" moniker entirely but it's essentially a tweaked version of the Caviar Green that is optimized for use in NAS (networked attached storage) devices and RAID setups. The Red is designed specifically to run in a 24x7 environment and doesn't have the Green's headparking energy-saving feature that causes lag and other issues in NAS systems. Red drives have also been tested and qualified compatible with a wide variety of NAS chipsets, is covered by 24x7 dedicated support, in addition to carrying a three year warranty instead of two. And last but not least, the WD Red supports TLER (time-limited error recovery), a feature found on Enterprise-class drives that is almost essential for RAID configurations to avoid data loss when errors are encountered.

Underside. 3TB model on the left, 1TB on the right.

The Red series is available in three sizes, 1TB, 2TB, and 3TB, and has received a upgrade in areal density compared to the most recent Caviar Greens. All three models sport 1TB platters, something that is quite evident after physically checking the 1TB and 3TB samples we received from Western Digital. Our 1TB sample weighs only 460 grams compared to to 640 grams for the 3TB model. Also, the 1TB version's casing is of standard thickness but on the underside there's a deep 10 mm inset, indicating the housing is much larger than necessary.
