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

Temperature display


HD Tune Pro gives us accurate read, write and access time results and for the last couple of years has gained popularity amongst reviewers. It is now considered a must have application for storage device testing.





Just as we stated, some benchmarks will show a substantial improvement like this one that uses sequential reads to stress the drive. The new firmware puts the M5 Pro in the same league with the 840 Pro 256GB, at least in this test. OCZ's Vector looks weak in this test, but OCZ tiers their single queue depth reads so you have bandwidth when multitasking applications.




The single queue depth write performance hasn't improved much with the new Xtreme firmware, but there was a noticeable improvement.



HD Tach - Sequential Write Performance after Random Writes




The performance following heavy random writes has historically been an issue with most SSDs using Marvell hardware. The M5 Pro has tamed the issue quite a bit, but it's still not in the same class as LSI SandForce controllers. When shopping for an SSD though you want the best all around solution and not just corner case performance unless you are looking to enhance a specific application.
