All this talk of software RAID is interesting. I am starting to think about what my next storage platform will be. I currently have a 50GB hardware RAID5 array in an aged Dell PowerEdge 2400, which I am soon to out grow (especially now Eryl and I have started doing a Photo-a-day this year).

I was planning on replacing it with a mini-itx box with a hardware SATA RAID card and four 300GB external disks for a 600GB + hotspare RAID5 array.

I had thought about using a Mac mini, USB2 disks and software RAID. I'd ruled it out because I though software RAID would be too slow.

Does anyone have any experience of how well software RAID on OSX works ?

P.S. If I went for the Mac mini I would wait for the Intel version, as I expect it to have a bit more grunt than the G4 one
