AFAIK all RAID arrays mirror the drives cache in the array cache until it hits platters. There may be some "cheating" hard drives (I heard that WD isn't always totally clear about cache policies) but Seagate and Hitachi professional grade drives definitely are OK. Hint: don't use desktop hard drives in any case because they probably cheat about cache synchronisation. I see that you may have been running rsync at the time of failure; there are quite a lot of quite unclear (to me at least) cases of XFS failures when running rsync to copy large amount of data.
