I am looking into performance issues we are having. We currently have a 4 drive RAID5 (3+1 fail over) and read performance sucks.
Looking at RAID1 with 2 drives (maybe more, any benefit?) but from what I have read around, RAID1 with madam doesn't seem to give any more performance over reads than a single drive, eg it would split the reads over the 2 drives.
Is linux software RAID1 better performance than single drive?
