Epic One- Jester's Report

RAID1 alone is good enough for redundancy, and that's what I've used on my desktop system for some time now. It's even saved my bacon once -- booting up to a "RAID array failed" message was heart-stopping, but no data was lost for some months while I was lazy about sending the bad drive back on an RMA.

RAID0+1 I'd be a little more scared of, because you can't simply take a single drive out, pop it in somewhere else, and have all the data automagically preserved. You'd need to transplant a pair, and also worry about the stripe settings. That said, 0+1 has a lot going for it, especially on the capacity/speed side.

On your regularly scheduled topic, it's interesting that Washington was your primary peaceful opponent -- it seems, given the geography, the most natural. I wonder what the statistics would be for Ghandi/Washington being the leading AI civ, especially compared to the (rarer) games where they were both stunted and Khan/Monty/Alex took the AI lead.

No, but you yank the bad drive, stick a new one in its place, rebuild the array, and continue on without blinking.

The stripping adds a lot of speed. Basically, everything in the computer world is moving in that direction. My new machine has dual-core CPU, dual-channel memory, and stripped (and mirrored) hard drives. It's all the same concept. Simultaneous access of two items running on the same bus speed is up to twice as fast as one item running on the same bus speed. Since the physical electronics are nearing their limits, we're finding new ways around the limits.

On the hard drives, the mirroring basically requires destruction of the entire box in one shot to threaten the data. Realistically, a head crash or other typical failure is simply not going to hit more than one drive at a time. Only outside destructive force could do that.

I -had been- running a single drive, no backup, no nothing, just taking my chances. Let me tell you, where I sit now feels immensely more safe! smile
