[TriLUG] FIO benchmarks

[Bill Farrow]

After last nights talk on FIO by Dwain Sims, I did some measurements
of various hard drives. The results tabled below are the "aggrb"
random read speeds.

Method
=========
sudo hdparm -i /dev/sda | grep Model

cat random-read-test.fio
  [random-read]
  rw=randread
  size=128m
  directory=/tmp/fio-testing/data

mkdir -p /tmp/fio-testing/data
fio random-read-test.fio

Results
========
KB/s       Hard Drive
 396        WD10EVVS
 692        WD800JD-75MSA1
 717        HDS721010KLA330
 833        WD20EARS-00MVWB0
 844        ST3160812AS
1096       ST1000DM003-1CH162
1195       WD1003FBYX-01Y7B1

Conclusion
=========
Don't use A/V "green" drives for your OS or high throughput workloads.
The $55 Seagate Barracuda ( ST1000DM003) is a great hard drive for the
price.
