raid performance
Hey y'all. A couple raid questions for you.
[1] I know that on newer machines, even though software raid is not the best performing solution, it is still a $0 solution so the performance improvements are worth it. But If I use os x's software raid on my g3 350, doing raid 1, is there going to be a lot of CPU overhead, so that the overall performance might actually decrease?
[2] If I run software raid 1 on the same idea channel, one master and one slave, is there going to be any read performance improvement? Might the performance actually degrade when compared to a non raid setup? Obviously redundancy is my priority here, but if the read performance is going to go down instead of up then i need to find a better solution.
Thanks!
John

As far as the usage of the CPU, I ran a scsi raid before on a G3 witha pci card and had no problem but you are wondering about software raid??hmmmmm will you be doing anything else with the G3 or is it basicly going to act as an external raid for other units? If thats the case then I would say it's worth converting into an external raid.
Hope this helps
