I have an early 2008 mac pro with the 300 GB HD that came in it. I have a Lacie RAID for back ups, but I would like a second HD in my machine to store files I use regularly and free up space on my start up disk. I have looked around and I am not sure what to get, I have looked around Apple's site but a lot of the drives seem to require early 2009. This is the HD I have..... Intel ESB2 AHCI: Vendor: Intel Product: ESB2 AHCI Speed: 3 Gigabit Description: AHCI Version 1.10 Supported Another drive like this would be sufficient for what I need but I guess I just don't know where to look. Plus when I start looking at other sites I get a little confused (A.K.A. I an Technically challenged). So any help in where to find a drive like this or a better alternative would be greatly appreciated. Thanks!
