Sumit,

There is no problem with RAW Devices. The difference between filesystem and raw is: you have to precreate the raw device before it is used for a tablespace.

Absolutely no problem with RAW devices.

In fact I would suggest: Use Raid 1+0 or 0+1 along with RAW devices. The thrughput will always be good.

So far, no benchmark results outbeat RAW Devices.
