Hi Peter,
I recently built a 3 drive RAID5 using the onboard SATA controllers on
an MCP55 based board and get around 115MB/s write and 141MB/s read.
A fourth drive was added some time later and after growing the array and
filesystem (XFS), saw 160MB/s write and 178MB/s read, with the array 60%
full.
Regards,
Richard
