Performance

We connected this drive to our test rig's SATA port to put it through our tailor-made test process. We used benchmarking tools such as H2Bench, HDTach, HD Tune and SiSoftware Sandra Professional.

H2Bench is a low-level hard drive testing utility and gives an indication of the raw performance of the drive. The drive was not formatted while we conducted this test; it did not hold any file system.

The drive returned a score of 199.5 MB/s in the "core test", which is one of the highest scores we have seen in this test. We also measured the access times for the whole disk and found them to be 12.59 ms for reading and 6.08 ms for writing, which are good scores.

HDTach RW 3.0.1.0 is yet another low-level test that does not require the hard drive to have a file system.



The overall performance is quite good, as you can see in the above screenshot.

HD Tune Pro 3.00 is a hard disk benchmarking utility capable of performing lower-level as well as file system benchmarks and displaying the result in the form of a graph. We ran the read as well as the write test to measure the transfer speeds, burst speeds and access time across the entire drive and obtained the results as in the figure.

Vertict says "...since there are options available that are a lot better in almost every aspect". Then why 4-STAR rating!!?

One star in the rating is reserved for the price and this drive lost one whole star there, but elsewhere it is a good drive and therefore doesn't lose any of the other four stars.
