7 For that kind of information, go with bonnie++
9 I've little else to add to the thread, except that I ran three Seagate
10 1.5TB 'green' drives in RAID5 for quite a while with very nice
11 perforance results. Access times were comfy, and I tended to get about
12 60MB/s continuous read and write speed. I hadn't learned about
13 bonnie++ yet, so I don't have any good benchmarks to show on that
14 front.
