Just did a new build... my OS drive is a 36G raptor thats getting 42mb/s and 19ms seeks in Sisoft sandra... my 150G in my personal rig is 74mb/s 6ms seeks. His other drive is a Maxtor thatt gets 50mb/s and 8ms seeks. What would make this raptor performance so crappy? The OS is even slow to load up. All drivers are loaded. Could it be a bad cable? Thx for any help. This is built using a Gigabyte P35-DS3R mobo and E4400 CPU @ 3.0ghz with 2gigs of memory.
