Western Digital 1 TB Caviar Green SATA Intellipower 32 MB Cache
Western Digital 1 TB Caviar Green SATA Intellipower 32 MB Cache Bulk/OEM Desktop Hard Drive WD10EADS
Available in capacities up to 2 TB, WD Caviar Green SATA hard drives reduce power consumption by up to 40 percentage and offer best-in-class acoustics and operating temperature. Based on WD’s exclusive GreenPower technology, these drives are designed to deliver power savings as the primary attribute. As hard drive capacities increase, the power required to run those drives increases as well. WD Caviar Green drives make it possible for energy-conscious customers to build systems with higher capacities and the right balance of system performance, ensured reliability, and energy conservation. They are ideal for PCs, external storage and other devices that require lower power consumption and cool, quiet operation.

WD engineering continues to impress me and I’ve been in the IT business for 20+ years as an engineer on all levels. When used in an Apple computer these drives impress with the hardware and OS ability to control the drive for increased performance. Some PC’s are being built with this capability as well, but even without it the on-board processor performs fantastic. I would however not recommend this drive in a server due to it’s variable spindle speed.
In an external enclosure SATA II through Firewire 800 sustained speeds matched a WD Black 1tb drive, basically maxing out the FW800 bandwidth. Through USB 2.0 they both performed identical as well but USB speeds are based on the external enclosures chip and since it’s Serial (USB) it’s ONE WAY at a time which makes it slow when compared to FW400/800. Temps in an iMac were less than 109* at most times, rarely exceeding 110* which also resulted in lower fan noise. Lower Heat, Less power generally equal longer life and higher reliability however these drives are still new. But as of this review our company has 2 in a NAS Enclosure running in RAID1 for the last 4 months non-stop without any issues.
The WD Black drives would be ideal when performance is what matters but in situations where energy consumption and more importantly heat is considered the ideal attribute these drives are best. The WD black is about 30% faster overall on either Mac/Pc. Spindle speed varies from 4200rpm-7200rpm on newer models, first generation varied 5400rpm-7200rpm. Both are able to stop altogether through a spin down feature however this will never “spin-down” on a windows based machine due to the indexing Windows employs that access’s the drive once every 3 seconds.
