I have two openvz servers running Centos 6.x both with 32GB of RAM. One is an Intel Xeon E3-1230 quad core with two 4TB 7200 SATA drives in software RAID1. The other is an old HP DL380 dual quad core with 8 750GB 2.5" SATA drives in hardware RAID6. I want to figure out which one has better random I/O performance to host a busy container. The DL380 currently has one failed drive in the RAID6 array until I get down to replace it, will that degrade performance? Is there an easy way to test disk I/O? On a plain Gigabyte file copy the software RAID1 box seems to be twice as fast.
