It depends on your needs. If you have a system with lots of concurrent activity, software RAID on IDE *will* be a bottleneck.
Actually IDE _MAY_ be a bottle neck, but software raid is faster than the cards the hardware raid solutions use in almost all cases. Go check the benchmarks. Your CPU scales up over time (as you upgrade), but that old raid controller is just as slow in two years as it is today. The CPU power in most servers today is just totally overkill and you might as well use it for something. Software raid more than holds its own on equal disks, with only the most EXPENSIVE hardware controllers being faster, and they usually gain this speed by supporting tons of cache. (which you could do with software raid just as easy). -- _____________________________________ John Andersen
