I'm completely new to the world of RAID. I think I want to use RAID 5 with three 1 TB drives to backup all my documents, pictures, music, projects, etc. I use both Ubuntu Linux 10.04 and Windows 7. I've had good luck with accessing NTFS in linux in the past, but Windows can't see ext3 or ext4.
What is a good solution using RAID for documents, pictures, music and projects (hopefully accessible by both operating systems) and still dual boot? I was thinking I'd have a separate drive for each OS and NTFS for the RAID hard drives. And to add on to that, if possible, mirror each OS drive. without mirroring, I'm up to 5 drives. With mirroring, I'm up to 7. I only have 6 SATA slots, but I assume I could use a card to have support for 8.
I'm not sure if this is an ambitious setup or typical for some. Thanks for any advice.
EDIT: Sorry I wasn't clear. I'm backing up my docs, music, etc. from two other computers to this computer. I'd like that backed up data to have some redundancy. Hence my question about RAID.
