Message: Hi Aqeel
There is no performance-benefit (that I ever heard of) in either of
them.
ASMLib (and the designated successor ASM Filter Driver, AFD) allow some
management-features, that your (or your OS administrators) need to do
manually if you use "raw" disks.
In terms of performance you can use whatever best suits your system
administration needs.

Jan

I note that you are 11g so I guess you could use them... but everyone
upgrades sometime.
