From a somewhat theoretical view, this is true for standard raid10 but Linux md raid10 is much more flexible as I understood it. You could do 2 copys over 2 disks, thats like standard 10. Or you could do 2 copys over 2 or 3 or ... x disks. Or you could do 3 copys over 3 or 4 or ... x disks. Do the math. See the manpage for md(4) and http://en.wikipedia.org/wiki/Non-standard_RAID_levels#Linux_MD_RAID_10 However, I have to admit that I have no experience with that but would like to hear about any disadvantages or if I am mislead. I am just interested. -- Kind Regards, Markus Falb
