I have had a 150 gig Raptor 10krpm drive as my system drive since I got this computer. The drive was dated at the time, but I wanted the 10krpm for my system drive. Fast forward 3 years to today: I only use about 70 gigs for my system drive. all it holds is OS X and apps, nothing else. All other files and documents are on other internal drives or external FW800 drives. So, my system drive doesn't need to be very big. Here's my questions/problems: 1. The raptor feels slower. It just feels less snappy, I can't explain why. It's barely at half capacity, so it's got plenty of free space. And I have 5 gigs of ram, so my Page Outs are very low. The only thing that creates alot of page outs is when I start a VMWare session of windows XP. VMWare the app runs off the Raptor, but my actual 25gig XP "virtual machine" file runs off an external FW800 drive. 2. The NOISE from it's read/write is starting to make my angry every time my computer is beachballing and all I can hear is the Raptor going WARHHHHGGGGWRRRRGGGGRRRWWAAAAARRRHHHHGGGGG for what seems like minutes. So I am wondering, now that it is 2010, if I went and bought a modern, regular 7200rpm drive, is it going to outperform the Raptor, and be quieter? Or since I only use 60gigs of a system drive, is getting a 500gig 7200rpm drive going to be pointless and not really improve any of my read/write speeds, except for maybe being a little quieter. I've read here that modern parallel read/write technology in drives actually outpaces the old Raptor. Or, should I just get the VelociRaptor 300gig 10krpm drive if I want to really improve my read/write? What's the current opinion or regular drives vs. the new VelociRaptor 300gig?
