Re: big drives (36 gig ) and Oracle performance

Sorry I'm a little late

The concern I would have concerns the number of drives. For best performance you want log files on separate disks than the datafiles. you may wish to split datafiles across disks as well. If so buying 36gig disks is a bit of waste of time as you still need (say) 5 of them.
