OK I have been reading up as much as I can but still got one dumb question.Using 2 similar hard drives,example raptor with 8mb buffer and a raptor with a 16mb buffer,is the performance gain pretty close to using 2 hard drives with the same buffer?

Buffer size is pretty much irrelevant. You can safely ignore it when you choose your RAID members.

Thats what I wanted to hear.Thanks.

Many RAID controllers (like the Perc 5/i) will include a few hundred megs of buffer. In this case the buffer on the HD is even more irrelevant.
