Simply Hard Drive Benchmark Using DD:

I used the dd command to do a drive benchmark comparison between my local IDE HD and my SATA mirrored RAID1 array, using a SYBA PCI SATA card. The results are quite slow considering it's a standard PCI bus card and software RAID.

Here are the results:

Create a 1GB file containing only zeros (bs=blocksize, count=number of blocks):

Command Structure:
# dd if=/dev/zero of=<output_folder_and_file> bs=1000 count=1000000

My Local Drive:
# dd if=/dev/zero of=/home/testfile.out bs=1000 count=1000000
1000000+0 records in
1000000+0 records out
1000000000 bytes transferred in 27.721 secs (36072634 bytes/sec)

My RAIDframe RAID1 Array on Std PCI to SATA Card :
# dd if=/dev/zero of=/raid0/testfile.out bs=1000 count=1000000
1000000+0 records in
1000000+0 records out
1000000000 bytes transferred in 304.635 secs (3282607 bytes/sec)

My CCD Mirrored Array on Std PCI to SATA Card :
# dd if=/dev/zero of=/ccd0/testfile.out bs=1000 count=1000000
1000000+0 records in
1000000+0 records out
1000000000 bytes transferred in 232.715 secs (4297088 bytes/sec)

Bonnie++

There is a port for a popular Linux benchmarking tool called bonnie++.

Installation:

# cd /usr/ports
# make search key=bonnie
# cd benchmarks/bonnie++
# make install
# make clean=depends

Execute:

# bonnie++

NOTE: This program installed but would not run correctly on my OpenBSD 4.5 system, I received errors about "file system is full" when it wasn't.
