I'm building a new dev computer. It will be running a few VMWare Worksation virtual machines - A dev machine running VS-2010, a build machine, a version-control machine, a web server for testing, a "personal" machine running office etc. I'll be connecting the computer to my stereo, so I'll also be running iTunes (possible on a dedicated VM) and I want the computer to be a silent one. (I'll probably use an Antec P183 case, an Antec CP-850 power supply, an i7-930, Sapphire HD5850 and an Asus Xonar Essence STX)
I was advised on Serverfault to use Raid10 for performance. Raid 10 uses 4 disks.
So, my question is as follows: In terms of heat, noise, reliability, warranty, price, capacity and performance, what would you suggest: A Raid10 4 disk array using eco-friendly disks such as the $94 1TB Western Digital Caviar Green, or one high performance disk such as the 2TB Western Digital Caviar Black at $280?
