I'm going to rebuild my system at home soon, and was planning to mirror
two drives. However, I was just looking up something about RAID, and on
wikipedia found some information about the Linux MD driver, and "near"
and
"far" RAID10.
Anyone have some opinions about them?
mark "or should that be how many opinions do folks have
about them?"
Raid 10 is a mirrored stripped set of at least 4 driver. You get the best of both worlds, data speed and data back up.. john On 3/4/2013 11:12 AM, m.roth at 5-cent.us wrote:> I'm going to rebuild my system at home soon, and was planning to mirror > two drives.

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
