HD Tune Pro 3.50 is an extended version of HD Tune which includes many new features such as write benchmark, secure erasing, AAM setting, folder usage view, disk monitor, command line parameters and file benchmark.
Benchmark Results: The OCZ Vertex 120GB SSD has more impressive performance numbers in HD Tune Pro 3.50 in both the read and write tests. All said and done, the average read speed was found to be 213.6MB/s with a write speed of 192.4MB/s. Both tests had an access time of 0.1ms and a CPU usage of ~2%.
Comparison Chart: When comparing the WD Scorpio Black 320GB (WD3200BJKT) to other popular 2.5-inch hard drives like the Western Digital Scorpio Blue 500GB and the Seagate Momentus 7200.3 320GB, you can see that it does well, although it is slower than the Seagate Momentus 7200.3 320GB hard drive in the transfer tests. It has the lowest access times of any hard drive we tested, but the solid state drives own that test.
64MB File Test
Benchmark Results: Running the built-in file benchmark test in HD Tune showed once again just how the drive performs with various file sizes. This test shows the Scorpio Black 320GB drive topping out at nearly 90MB/sec in both the read and write tests.
