I found a thread on the intel 320 series ssds. seems like some sleep issues and dead drives. http://communities.intel.com/thread/22227?start=0&tstart=0 I have been reading it makes me a bit nervous as I have a 600gb unit costing over 1k. well 725 after discount. Since I purchased it on ebay I do have a warranty on it via square trade. So as a heads up intel is joining the club of DOA. Although most users have a problem with it in pc's not macs at least on the intel forum thread.
