HD Tune v4.01 – Random Access

The random access read and write test is a very important performance area to look at on solid state drives as some controllers have problems with random writes. In recent years the controllers have improved and the firmware has been better optimized for random read and write performance.

Random Access Read Test Results:

Benchmark Results: When it comes to the random access read performance test the WD VelociRaptor 600GB HDD did fairly well with solid average access times for a hard drive in both IOPS and MB/s. The 4KB read speed on the WD VelociRaptor 600GB HDD was 0.571MB/s.

4KB Random Access Write File Test Results Chart:

Benchmark Results: Many of our readers have asked for a chart showing side-by-side comparisons of the drives we have tested in the 4KB random access write test. You can see from this chart that the WD VelociRaptor 600GB HDD had a tough time keeping up in random access write tests at 4KB, but it was slightly faster than the WD VelociRaptor 300GB hard drive that this model replaces as the flagship enthusiast hard drive for WDC.
