Testing
The system in today's tests will be a system
build based on the ASUS P6T Deluxe. This has become our primary test
rig for testing hard drives.

For
the bulk of the hard drive benchmarking I'll be using Hard Drive Tach. HD Tach has proven very
reliable for us over the years and I like to stick with what works.
However, I will include a few HD Tune benchmarks as well.
Single Hard Drive Test
HD Tach:
Quick Bench / 8MB Zones
Immediately I was relieved to learn that we would NOT see a dramatic
performance drop from the Barracuda 7200.12 to the Barracuda LP. Also
keep in mind that the 7200.12 drives are 7,200 rpm hard drives while the
LP is only 5,900 rpm. That alone should have been a dramatic hit to
performance, but so far I'm just not seeing it. But before we get too
excited, let's move on to the long bench.

Single Hard Drive Test
HD Tach: Long
Bench / 32MB Zones
Once again, the long bench shows some pretty decent numbers that are
just slightly below that of the 7200.12 desktop hard drive. Again, not a
big deal due to the fact that the LP is only 5,900 rpm.

Tune
Even HD Tune is showing some pretty good numbers. Slightly slower that
previous "high performance" hard drives, but not by much.

Next let's test RAID performance and then show a side by side comparison
of the LP and the 7200.12.
