RAID in PowerMac G4

[d88co88]

Hi, I have a PowerMac G4 I'd like to use as an "experimental" backup machine. I am looking to try and make a RAID setup in it, and I'm no expert with that. I'm wondering if this is even possible, first. I'm also wondering if I can do this with 2 40 gb drives and a 20 gb drive. I want to make it so it appears as 1 drive. I'd be using tiger and a software RAID if that is of any relevance. Thanks!

Specs:
500 MHz PowerPC G4
640 MB SDRAM
No hard drives currently

Here is step by step from apple.

You want to go with the concatenated

But remember: it's like RAID 0 - one of HDDs will die - your data is gone. It isn't reliable solution for backups. Especially if you use old, used HDDs (40 & 20GB aren't manufactured from some time AFAIK).

Thanks for that link!

I know the risks, I just want to use it as an experimental backup. I already have a "real" backup.

Keep us posted. I want to do a raid in my QS with two 1tb sata drives

I will, I'm planning on doing it on Christmas. Will my power supply even support this many drives? Could it support another one with an ATA card or something?

It should support 3 hard drives total. You can get aWay with 4 if you remove the optical drive. Anymore then that and you will be seriously taxing the ps. If it were me I would also remove the video card after I set it up and just remote login to it
