Okay, I've been popping in and out of these forums for a while, but only actually signed up today to make a few replies to threads here that are looking at similar things to me. Basically what I'm trying to do with my PowerMac G5 (Dual 2.5ghz) is remove as many of the bottlenecks as I can. The first step for this was to get some more RAM, you might not want to think it but 1gb does actually limit such a fast machine, 2gb ought to help a lot there. However, the problem that is still left is that of actually getting information into this 2gb of RAM in the first place, namely from a hard-drive. The only internal drive I have is the 160gb SATA drive my G5 came with (7200rpm, around 60mb/sec transfer rate). Although this is fast, it is still a limiting factor in the G5. At first I looked at simply getting a faster single hard-drive, so I looked at the Western Digital Raptor, which is a formidable drive with 74gb space and a 10,000rpm speed, but for all it boasts it sounds like it isn't as big a step-up as I would like, add to that the cost of £120 (or £75 for the 36gb version) and it really doesn't pack all that much power-per-pound. So what I'm now looking at is instead getting two much cheaper (and still very speedy) 80gb drives, the ones that I have found are actually surprisingly inexpensive at £38 a piece: http://www.pixmania.co.uk/uk/uk/36288/art/seagate/hard-drive-barracuda-7200.html So that's the two hard-drives out of the way. What next? Well, my G5 only has one spare drive spot, and I don't want to replace my 160gb drive, so what I now need is a good SATA Raid controller PCI card which will allow me to attach two or more internal hard-drives. And now I'm stuck. I keep finding such cards that offer Mac compatibility, but I then can't find any for the UK, with the expection of one over-priced card at £65 for only two connections (a similar card by a different manufacter would cost around $55). So I've found my way back here to ask if anyone knows of a good card for the UK, I'm looking around £40 (£50 tops) I think to keep my RAID assembly around the £125 mark (plus any extra cables I need). While I'm at it I think I'll also ask, since I'm installing two internal drives (both on the card I think, leaving my spare built-in bay free for a bigger drive later) then I'd also like to know what cables I'll need, most importantly power and where I connect these. I'm under the impression that it goes in the back of the SuperDrive, but I'm not certain what I need for this.
