It is.  Yes, there's separate module for raid10, but what it - basically -
does is the same as raid0 module over two raid1 modules will do.  It's
just a bit more efficient (less levels, more room for optimisations),
easy to use (you'll have single array instead of at least 3), and a bit
more flexible;  at the same way it's less widely tested...

But the end result is basically the same for both ways.
