Hi all, I have a Mac Mini (1,1) 2006 model that I'm upgrading (with a T7600 Core 2 Duo 2.33 Ghz Processor, 4 GB of RAM (3.3 GB usable), and a faster hard drive than the ****** 5400 rpm 80GB drive that is currently sitting in it. Not sure if I should get the 500GB or the 128GB. The 500GB has a 4GB SSD so commonly used applications will us that. Probably will never use the full 500GB - maybe up to 100GB tops with movies. The 500GB hybrid will also cost $20 cheaper (I can get it brand new for $40 whereas the Crucial M4 I can get for $60 total). I really like how SSDs make everything load so much more quickly and it makes the computer feel "brand new and minty." I am on a budget, and I am also considering re-sale value as well if I ever want to sell it. I think a 500GB 7200 RPM in a Mac Mini is probably more appealing to people than a small 128GB SSD. I'm leaning towards the 500GB w/ 4gb ssd, but I'm not sure if the whole "TRIM" thing will be a problem or if I need to enable it for the 500GB w/4gb ssd one. The Contenders: Seagate Momentus XT 500GB/4GB SSD/7200 RPM versus: Crucial M4 128GB SSD SATA 3 Key Notes: My Mac Mini (2006 Model) can only read SATA I (1.5 Gbps) and not SATA II or III so the speed benefits of SATA II or III won't be utilized. Edit: Also, when upgrading the HD, do I need any special tools or just the typical ones?
