First and foremost, download Neil Brown's mdadm package.  It makes
kernel software RAID a piece of cake!  (apt-get install mdadm will work
if you run Debian)

Second:
# mdadm --create /dev/md0 --chunk=X --level=0 --raid-disks=2 /dev/disk1 /dev/disk2

The chunksize is an integer parameter that set how wide the stripes are
- playing with this value can change performance a lot, so definately do
some benchmarking!

*HOWEVER* - I wonder if you're not asking for a disaster.  RAID0 has no
provision of reliability.  ie, if one of those disks starts having
problems, you've lost all your data.  I would be very reluctant to use
RAID0 as permanent storage for any of my music - there's too much risk.

Let me agree with other posters that it's probably overkill, especially
considering the data loss potential.  I do my GNU/Linux recording work
to a partition that's actually a mirrored RAID1 pair (slower than a
single disk) and I've never had problems.
