Firstoff, installing a hard drive on the Mac Pro is probably easier than adding RAM and almost as easy as opening the computer. The things screw onto the little trays and slide in. There is no futzing with cables or ANYTHING, it's so extremely easy.Trippy Jr said:Because most people don't want to install bits and pieces themselves, even on a pro machine.
And you may think it's so damn stupid, and I primarily listed it as an example, but anyway... my Mac Pro is coming with the first drive upgraded to a 500GB. Why? Because I operate three computers at any one time. One is a desktop, which will shortly be the Mac Pro, and the other two are laptops - a PB/MBP and a Windows laptop.
So, as you see, outside of the Mac Pro, I will have no use for a SATA drive. So, rather than buy a 160, swap it out and stick in a new 500, I'll have a 500 delivered, buy three more 500s, and not be left over with a useless 160.
You do realize that you can have different-sized hard drives installed in your computer, right? So in the scenario I was talking about, you'd end up with the 250GB that you could use as your system drive, and then the 160GB that you could, for example, put extra files on, put stored video on, put your iTunes music library on, etc and thus save more space on your 250GB. So essentially, for $15 more, you're getting 410MB of total system storage versus 250.
