Where did you hear that?

% head -n 1 /proc/mdstat
Personalities : [raid0] [raid1] [raid10] [*raid6*] [raid5] [raid4]

% zgrep CONFIG_MD_RAID456 /proc/config.gz
CONFIG_MD_RAID456=y

Also, I don't have any enterprise experience with Linux RAID10, so I can't
comment on its overall reliability, but don't forget to take it into
consideration. It's much more flexible than RAID1+0, and should have better
performance characteristics under certain circumstances, too.
