I've had zero issues with my G1's (knock on wood). It sounds like you may have just been unlucky with yours as it would appear to have been a hardware failure. Other's here are having file system issues with the G2 drives in RAID with 10.6.2. So far, it seems the G1's in RAID0 on 10.6.2 are fine. At least my prior array of two drives and this stripe of 3 seem to perform flawlessly. At any rate, living on the bleeding edge does require a good backup strategy in the event the worst should happen.
