Keep in mind that artificial benchmarks don't always give realistic
results on an unloaded system. If the system is busy running an actual
application (like a database), and does not have to spend resources doing
RAID, hardware gives you more of a benefit. This is especially true after a
disk fails and you're doing a rebuild.
