PPS. You might have a reason, but it would be irresponsible not to point out that by using RAID0 you now have an exponential risk of losing all of that data.
The Raid0 is simply a large disk pool for temporary data storage. Not the way I would build this, but I am simply managing the hardware for this individual, and he has been warned about the loss of data due to the single point of failure, especially without backing this data up to somewhere I can get to it with tape
Thanks again Michael

OK, I won't beat this to death, as I know there are always exceptions to the rules, BUT a 4-way RAID0 is far more likely to fail than just a single disk, so I wouldn't consider it a single point of failure. I'm not sure about the math right now, but it's something like 2^4 (16) or even 4! (24) time more likely to fail than a single disk.
