Caching isn't RAID.  If you want caching, see dm-cache or bcache.

RAID2 isn't something that really exists in the industry.  According to
wikipedia, it was once used to refer to a bit level, rather than block
level type of striping with parity.  These people seem to be making up
their own system and it sounds like snakeoil.

I can't tell if you are talking about one drive, or two.  You can't
magically speed up a single drive nor increase its longetivity.

Which two?  raid10 is "2 raids in 1" ( raid0 and raid1 ).
