What problem do you have that you are trying to solve?

An observation: with RAID0, you will lose all the data on the RAID device
if any of the underlying physical devices fail. You're already three years
nearer the time when the first of those disks to fail will actually do so.
You don't say what size your RAID0 partition is, but you may want to
consider buying two disks that are each (at least) the size of your RAID0
partition, and implementing them as RAID1, therefore giving you some fault
tolerance. If you do that, set up mdadm to email you if the array becomes
degraded.
