A logical drive is a partition of a physical drive. It can be a complete partition of a drive or a partial partition.A physical drive is where you determine performance. A single physical drive offers no protection and doesn't perform as well as a RAID drive (usually).
A SAN typically bundles physical drives into arrays that can have a logical drive presented to Windows.
I'm not sure what you mean by "works the same". A SAN is a much more complicated I/O subsystem.
thks for your info...
will it improve the performance by spliting the physical drive into many logical drive in SAN or not ?
