I believe he was referring to a SAN configuration - and yes, MS does not recommend using large raid 5 sets on a SAN. Raid 10 is the preferred method.
Exchange 2k writes in small 4k blocks. Using raid 10 with 15K drives would really up the performance. It also matters how the data files are broken up in Exchange. If you email me directly I can provide some performance counters which can help pinpoint the bottle neck.
