Striped was always flakey in my experience. It was used so if drive fails you have back up. With todays cheap external drives for back up I would use extra drive as storage.
Striped stores some of the data on one drive and some on the other, and yes it has been flakey in my experience also.
Never saw a speed benefit to speak of either.
The other way (Raid 1 I think) is reduntant so if a drive fails you still have the entire data.
with striped if a drive fails you have half of the data and the total system can not be recovered.
Mirrored (RAID 1) is redundant and both drives hold all the data.
Striped (RAID 2) is for making the computer faster by cutting down the data searching over a single drive.
