Re: [CentOS] question on RAID performance

2008-04-10 Thread John J. Lee
If you want to higher R/W performance, you should go for raid0. raid0 fragments the data into the number of disks and distributes them. It gains a big performance. One drive fails, however, all data gone. raid5's benefit is not the speed but the effective space usage with the least data redundancy

I am currently running 7 raid10 data servers. I can say read speed increases but I doubt the write speed comparing to non raid setup. The main advantage of the raid is redundancy but not the performance. If you want to boost the disk performance, go for the faster drive with more than 10,000rpm s
