Top Forums UNIX for Advanced & Expert Users How to test RAID10 array performance [Debian Wheezy]? Post 302918751 by drl on Thursday 25th of September 2014 09:41:07 AM

Hi.

Here is a report on several disk configurations that was done in 2009 using benchmark code bonnie++ (32-bit 2-CPU Athlon box):
Code:
Description-en: Hard drive benchmark suite.
 It is called Bonnie++ because it was based on the Bonnie program.  This
 program also tests performance with creating large numbers of files.

which can be found in the Debian repositories.

Currently I use RAID10 with 4 SATA disks with LVM on top of the RAID on a virtual-machine server. I have not run the bonnie++ benchmarks on that system, but perhaps I will now that I see that there is some interest.

The only reason I would use RAID10 with less than 4 disks is practice (as with setup, etc), not for performance.

Best wishes ... cheers, drl
