The other plus is that growing linear arrays is cake. They just get

adding the device, then converting back to raid0. And further, linear
grow can be any size drive, whereas clearly with raid0 the drive sizes
must all be the same.
Nice!
I have been learning about md arrays and have seen the details about
growing operation but it's another aspect which I wasn't thinking about
at first.
For now I am not planning any storage but it might come handy later on.
Thanks,
