I posted this as one of my questions in another forum but I realized it's more appropriate here I'm planning on getting a G5 DP2.5. If I get the 160 gig and buy another 3rd party SATA 160GB 7200RPM drive (guaranteed to be a DIFFERENT make/model), can I link them with soft raid and boot off them? Also, is it reliable? is it faster? by how much?
