I just finished setting up a RAID5 array of four new Seagate IDE
disks. To my surprise, the read speed of this array is only 28 MB/s,
even though the individual disks report >40 MB/s, all as per hdparm
-t. Is this what it's supposed to be like? I read in the
Software-RAID-HOWTO that read performance of RAID5 would be similar to
RAID0.
