Building File Server, Best/Safest RAID Setup??

[jdl8422]

I am currently building a RAID setup for storage of iTunes and other files. I have 4 hard drive spots to work with. I have been throwing around a few options. Any suggestions on the safest way of doing this would be great!

Option 1:
4 x 1.5TB (2x1.5TB RAID 0 + 2x1.5TB RAID 0 Clone) What would be the worst case scenario with this? if one hard drive fails I would just use the clone or vice versa.

Option 2:
4 x 1.5TB RAID 1 with no clone. Which of these is the better option? or is there an option 3?

Since you can't do RAID 5 without a card the RAID 10 (option 1) setup is likely
your best bet.

No matter what you still only end up with 3TB. If you could do RAID 5 you would end up with roughly 4190TB.

I agree, RAID 0+1 seems to be the best option. If OP did RAID 1, he would end up with 1.5TB I think because the data is mirrored to all drives

If you could do RAID 5 you would end up with roughly 4190TB

I didn't know RAID 5 can increase the total capacity by that much 4.19PB sounds massive

I am using a G4 Quicksilver and I have 2 sonnet tempo SATA cards. Each card has 2 SATA ports. I'm not really sure if I can do a RAID 0+1. Sounds like a good idea if I can. Would just setting up two RAID 0 and using carbon copy to clone one RAID 0 to other work just as well?

Of course it would, it's just software "RAID 1" but does the same thing
