Never mind, didn't notice the subject said RAID 0, I took the body of the
message to mean raid 1 or 5

But would it - necessarily - make sense ? if you use multiple swap-paritions, Linux
will alternate between them, provided you give

You are right -- I have not benchmarked yet. Speed is not that important to
me. I am really only concerned with the redundancy. I just thought that
hdparm would be a good test of single threaded sequential reads( but I have no
idea if that is true ).
A few kernels ago I tried the raid-1 read b

I have often had the same question.
I run in a raid-1 configuration and my read performance( mesured with hdparm
-t ) on the md devices is about half of that of the ha[a-z] devices. I had
always assumed that reads where ballanced among the devices that made up the
raid-1 volume and that reads wo
Hi,
I've successfully set up SW-RAID0 with Kernel 2.4.3 and Raidtools 0.9.
I did this to increase the performance of my HD, but nothig happens.
hdparm -t /dev/md0 : 20.25 MB/sec
hdparm -t /dev/hda : 20.51 MB/sec
hdaprm -t /dev/hdc : 20.71 MB/sec
I thougt the performnace of RAID0 should near 40MB/s
17 matches
