I have been looking at a lot of different options on higher-capacity storage with redundancy. Has anyone looked into setting up a hardware RAID system that has over 4TB and what did you do? I really would like to have at least 4TB but I also want to run MAC OS on an SSD drive. I am in design and use a lot of large files, so this is really the problem I am trying to solve. Idea One: So I have been mulling over the idea of getting a RAID card (RocketRaid 3520) and running RAID5 with 4 2tb drives. I would need to figure out where to put the SSD drive. The RAID card should also boost performance. Idea Two: Running 4 2tb drives as RAID1+0 and figuring out how to also use an SSD to run the OS as a 5th drive (would I need a RAID card still? Can I run as Firewire or something?). This isn't my ideal choice and it doesn't involve RAID cards and extra headache. Thoughts: I have read that recovering a RAID5 is horrible and also don't want to have to worry about future conflicts with a RAID card but it should boost my speed considerably? I don't know if I understand RAID1+0 and how it performs and works if a drive fails - sure that is googleable. I am also thinking about using an online backup as well, like Mozy or whatever. Anyone have any other suggestions on a set up or see any issues? I really would appreciate it as this is just overwhelming. Thanks in advance.
