The HD Tune Pro random performance test is possibly one of the most relevant benchmarks that we use. First up we have the read results, and when running the 512 byte test the traditional hard drive produced a throughput of just 0.04MB/s. The Intel X25-M achieved 5.5MB/s, while the Indilinx Barefoot SSDs were limited to 4.8MB/s, which included the A-Data S592 128GB and OCZ Agility. The Samsung SSDs were a bit slower, with the Corsair P Series 128GB reaching 3.5MB/s. The 4KB test varied only slightly when comparing the Indilinx Barefoot, Samsung and Intel SSDs. The results fluctuated between 22MB/s and 27MB/s with the OCZ Vertex Turbo delivering the best result. The 64KB test favored the Intel X25-M, while the Indilinx Barefoot SSDs were able to outperform the Samsung competition. Finally the 1MB test strongly favored the X25-M, while the Samsung SSDs were slower than the Indilinx Barefoot SSDs, with the exception of the A-Data S592 128GB which was quite slow.

The OCZ Vertex Turbo dominated the HD Tune Pro write test, delivering the best result for the 512 byte, 4KB, 64KB, 1MB and random tests. The Samsung based SSDs were particularly poor performers in this test as they were only able to match the hard drive in the 1MB and random tests.
The HD Tune Pro random write test proves why the G.Skill Titan SSDs should not be used as OS (Operating System) drives, as their performance was terrible. While the random write performance of the Intel X25-M was impressive when handling 4KB and smaller files, it was overwhelmed by the Indilinx Barefoot SSDs once the file size exceeded 64KB. Even the random performance, which incorporates all file sizes, was significantly better on the Indilinx Barefoot SSDs. The Samsung SSDs on the other hand, such as the Corsair P Series, suffered in this test as they were significantly slower than both the Intel and Indilinx competition.
