I have a customer with a IBM X206m running two 160Gb SATA in RAID 1 configuration. I want to add another 500GB SATA drive to the server as a sort of backup drive for extra data. They are a media company have alot of large files to store. Is this feasable without breaking the curent Raid Array. I just want the 500Gb drive to show up as an additional drive and to be no part of the current raid.
