Summary
Benchmarks
We used a traditional benchmark such as HDTUNE but included our favourite “IOMeter”.
IOMeter measures IOPS (Input Output Per Second) at different user configuration
settings. We completed a set number of sequential and random tests to give a true
indication of the performance on this drive.

small random reads and a 40%
gain in random writes. These
are fairly significant and as we
indicated with our initial article
on the SATA3 interface, we
found it increased random IOPS
operations. Looking at random
write results as compared to the
Corsair Nova SSD, we saw that
this VelociRaptor much faster
than the SATA2 version but is
in fact, still a long way behind
a mid-range SSD for random
IOPS. Moving on to sequential
operations we gathered that
there’s only a small difference
in performance between the two
drives, this could indicate that
the actual speed of the drives
are very similar and the main
difference is the SATA3 interface.
After all the testing we
wondered if there’s anything
we couldn’t have expected from
this drive and it turned out
that the SATA2 drive is actually
faster in large random read
operations, this is defiantly
unexpected and something we
were unable find an answer
for. Unfortunately for this drive,
large random read operations
are a fairly regular occurrence
in daily use and it’s concerning
that the SATA3 disk didn’t show
any improvement here. When
we plugged our SATA3 drive into
the SATA2 interface we did see
our results drop slightly, so we
can definitively say there is some
advantage to a high RPM optical
disk using the SATA3 interface at
least in most situations.?
[ Pro ]
We’ve been fans of Western
Digital’s range of Raptor
and VelociRaptor drives
for a while and this drive
is another great addition
to the range, bringing
an increase in size, IOPS
gains from the SATA3
interface as well as a
20% improvement to read
and write operations. We
actually use these drives
as our main benchmark
drives as they are quite
robust, have ample room
