You cannot get more than about 200MB/s out of a RAID1 setup, not even
with
15krpm SAS drives. the RAID1 will never be faster than a single disk.
How

It can read faster than a single disk by combining reads from different
sectors on different disks. I think your assertion is incorrect for
reading, though not for writing.
