So I added a HD to my '09 octad, the samsung ecogreen f2 1.5tb (same ones that Tesselator has in his raid setup). I moved my home folder to this new drive so it had a nice cozy big space to grow (my apps are only 50gb, but home folder is around 370gb, so filling up the original 640gb drive). Since doing this I have had a MAJOR slowdown, I mean it feels like a 386 at times, my mouse will studder and keyboard will take a while to react, I also have trouble single and double clicking and then it will clear up only to return (hmmm almost sounds like a mouse driver issue... I'll update logitec as well but anyway)... I've run onyx to do all the permissions (of which I can only run on the original drive for some reason) and scripts (daily, weekly, monthly etc) I'm 99.95% sure that the drive shouldn't cause these issues... Any suggestions? Should I just move over my entire system to the new drive (I wanted to keep the apps on the 7200rpm drive for launch speed) leaving the old for bootcamp or something??
