Any machines we have that have raid 0 also have raid 1 (0+1) in that there is a mirror of the raid 0 array.

As for the on the fly replication.. what happens if the same record is updated on 2 machines at the same time. For example, we have a counter field to see how many times an image has been loaded. Is the lag of waitng for the replication going to affect the data? I know the replication is on the fly, but say you have 4 machines load balanced and all are at 80% useage.. its not going to be able to instantly replicate data between all the servers and there is a possiblity of something not getting updated properly.

Thanks for the help, there doesn't seem to be alot of help out there on this subject.
