Ok, I've got a semi-hypothetical question about a reasonably safe, comparitively cheap RAID solution for a G5 owner. I'm thinking out loud here, but here's the executive summary: I've got a G5 and am looking for some hardware data safety. I'm thinking an internal RAID1 array, plus an external RAID5 array, would offer the best combination of price and reliability. Which would work better, though: a hardware RAID5 box ($850 + drives), or a roll-your-own Linux server ($550 + drives + a lot of hassle)? Long form, for those interested in my logic: My theory is basically that, since the G5 only has two internal bays and there are currently no RAID-capable SATA cards for the Mac (that I know of) to combine with one of those multi-internal-drive brackets (plus they increase fan noise), the most obvious solution is a pair of RAID 1 drives internal to the G5 (either Raptors or 250GB IBMs, depending on the taste for speed vs. space, presumably using Apple's software RAID) for OS and fast, readilly accessable data, and a RAID5 array external for bulk storage (video projects, etc) with security without having to mirror the whole mess. There would of course be an additional, offline backup of the really important stuff floating around somewhere, but I'm more concerned with hardware failure than my stupidity or data corruption in most cases. The question, assuming there isn't a more logical option that I'm missing, is what is the best combination of data safety, power efficiency, convienence, and price for the external array. The options I've thought of: Option 1) Hardware FW800 RAID5 Box. The best deals I've found are from FireWire Depot on the QUAD5 LCD RAID ($1200, 5 bays with no drives) or Q3 RAID 5 ($850, 3 bays with no drives). Fill either one up with 250GB drives, and you've got a heap of available, automatically backed-up storage. Downside: pricy. I'm also worried about how twitchy they are; all the hardware failure security in the world is useless if there's some obscure Mac incompatiblity that corrupts the data on it. Anybody ever used either of these things? Do they work as well as advertised, or are they better in theory than in practice? Kano also makes a nice looking 3 drive RAID5 box, but they only ship with drives, and charge too much for them. Option 2) Build a cheapie PC in a relatively small case, put a Promise RAID card and a gigabit card in it, install a stripped down Linux distro, and hook everything together with a Gigabit hub. I estimate this would come in at a little over $500 (sans drives) if I shop carefully, and would give up to 4 drives in a RAID5 configuration. The advantages of this would be that it would have the other advantages of a server, and I could also connect to it via VNC and maybe rune WINE or something to give myself speedier Windows "emulation" for the rare days when I need it. The downside would be the latency of the ethernet connection, which I'm guessing wouldn't be sufficient for things like video capture. It'd also be a pain to get working initially. So... if anybody is still reading, what do you think?
