Thanks Folks for the support

HP who co-anchor this benchmark gave the following:-
system device block size(think this is the O.S. block size) = 1K Base page size = 4K.
DB_block_size = 8K
This seemingly indicates an O.S. Block size of 1K though I have never before heard of such a size... usually knew O.S. Block size to be 512 Bytes (1/2 KB).

My Reasons for preferring Mounted F.S. over ASM in a NON-RAc scenario are mostly the same as given by Jared:-
- F.S. are a Comfort zone & I have historically & traditionally used them for a while.
- Additional instance for ASM
- file management is simpler
- storage admins have easy direct access to see what's on disk.
