Well, in that case, onboard RAID really is your only option unless you
a) invest money in a real hardware RAID controller
b) replace dual-booting with virtualization

MD is the kernel subsystem for software RAID. Device mapper (or dm) is
used for onboard RAID, among other things. In the kernel, they use the
same code-base but their interfaces and purposes are different.

With "locking in on their disk format" I meant that with onboard RAID,
your chances are slim that you can move the disks to another PC and they
will be readable. With software RAID, every recent Linux system will be
able to access it and with _real_ hardware RAID, you can at least expect
to find compatible hardware and support for many years.

BTW: Please make sure to send your response to the mailing list, not my
personal address. And don't top-post, either. Put your response below
the quoted text (I moved your response manually to right place). This
makes reading long threads easier.

Hope this helps,
