Tony,
I like to use RAID 10 when I can, much faster than 5.
Are you saying that even thou there is a single logical drive that the
raid controller built, there is a difference at the windows level when
we create seperate O/S logical drives? Or, are you refering back to the
Raid 5 vs. Raid 1??
I'd like to clarity on this point as I am going to building new
servers.
