Hi,
I`m running raidtools-0.41 on a P75. I'm using raid1 because I know there
will be a day when one of my disks will fail. There are three ide disks and
a cdrom.
Running hdparm on md0 and its components gives me:
dilbert:/root # hdparm -tT /dev/hdd1 /dev/hda6 /dev/md0
/dev/hdd1:
Timing buffer-cache reads: 64 MB in 3.76 seconds =17.02 MB/sec
Timing buffered disk reads: 32 MB in 11.64 seconds = 2.75 MB/sec
/dev/hda6:
Timing buffer-cache reads: 64 MB in 3.78 seconds =16.93 MB/sec
Timing buffered disk reads: 32 MB in 10.55 seconds = 3.03 MB/sec
/dev/md0:
Timing buffer-cache reads: 64 MB in 4.03 seconds =15.88 MB/sec
Timing buffered disk reads: 32 MB in 15.11 seconds = 2.12 MB/sec
Why is this?
Any hints?
Thanx,
Joachim
