You can of course build a layered raid 0 above some raid1 arrays, but linux md raid10 is another beast. Actually you can build a raid10 with only 2 disks. The theoretical benefit is that is is striped, so even one single process benefits from it. If you use raid 1 a single process does use only 1 disk as far as I know. http://en.wikipedia.org/wiki/RAID#Non-standard_levels One disadvantage is that you can not grow or expand it easily, which means it is inflexible, which is why did not want to use it. -- Kind Regards, Markus
