Yes and no.
It will be as slow as any common harddrive for write operations, but it
will be extremely fast for read operations. Now, what is your expected
usage profile?
Ez.

I once did some benchmarks for a client and showed that even a
mirror of
three disks (yes, every sector written 3 times) the write time penelty
was extremely small, however reading speed jumped practically in a
Yes but these were all practically identical disks - Guy's response
was about my idea to mirror a RAM disk with a regular magnetic media
disk, which would mean that that this volume will be as slow as the
magnetic media, so loosing the advantage of investing in a RAM disk.
