Are there any downside of creating LVM using raided device?

http://serverfault.com – I want to use the performance of RAID-0 and flexibility of LVM for managing storage. I have created RAID-0 using two disk of equal size and then created a PV and included in VG. Then I have created LV of desired size. I understand that if any device in RAID array fails the complete array will also fail. I am planning to use this stack in my production, so are there any other downside of using RAID-0 with LVM ?
