HD Tune Pro gives us accurate read, write and access time results and for the last couple of years has been gaining popularity amongst reviewers. It is now considered a must have application for storage device testing.
While looking at the charts of 2.5" drives today, we are mainly going to focus on the previous Constellation Series and the WD VelociRaptor 600GB, the only other enterprise class 2.5" drive.
The new Constellation.2 is clearly faster than last years model. Here we see that the average read speed of the new version is actually faster than last years maximum speed.
The same can be said about the write speed. Here we see that Seagate has made the 2.5" SATA Constellation.2 quite a bit faster.
