Is there an advantage either way on such a >large array? Doesn't that depend on what sort of backup solution you're planning, and the level of "criticalness" of the backups saved? Some say that for more serious raid solutions, hardware is the way to go, while software raids are sort of a middle-road. Me, I usually go with software raid. I've had one too many hardware raid failures where I haven't been able to restore the data contained. With software raid a restore has always worked fine for me, especially broken raids in Windows. While raid in Windows isn't overly performance-inclined, I've come to appreciate the software ditto in linux - both performance and stability is top-notch IMHO. With today's CPU-performance and RAM available, software raids are not a problem to power. -- /Sorin
