HD Tune is a Hard Disk utility which has the following functions:
Benchmark: Measures the performance
Info: Shows detailed information
Health: Checks the health status by using SMART
Error Scan: Scans the surface for errors
HD Tune Pro gives us accurate read, write, and access time results. For the past couple of years, HD Tune Pro has gained popularity amongst reviewers; it is now considered a must-have application for storage device testing.
While the performance isn't exactly the same as the Vertex 4, Vector, or Vector 150, the profile of the test results on the graph is very similar.
Q Series Pro also has the same performance write profile as the OCZ drives when we write 64KB blocks to it. The drive writes at high speed for 50% of the test, and then drops down to just over 105 MB/s for the second half.
HD Tach - Sequential Write Performance after Random Writes
After running the drive through random write tests, we measure the 128KB sequential performance in HD Tach. The lack of a DRAM buffer to store the map translation layer may be why the performance drops so much after random writes. Regardless of the reason, the Q Series Pro can get in pretty bad shape after a random write workload.
