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 and for the last couple of years has gained popularity amongst reviewers. It is now considered a must have application for storage device testing.
Our OCZ Vertex 3.20 120GB arrived well tested with 1TB of data written to the flash and around 27 hours on the clock. We normally don't see this, but media sample are sometimes tested before shipping out for reviews. Our testing methodology states that a drive starts from fresh out of box condition and then we chip away at the flash in the early tests and get to true consumer steady state by the middle of the review.
The first thing we did was secure erase the OCZ Vertex 3.20, but from the results above I'm not entirely sure we managed to get the drive to steady state. We used two tools, OCZ's SSD Tool and later Parted Magic after seeing the performance delivered after using OCZ's official secure erase.
In this test in what should have been a clean state, Vertex 3.20 is down quite a bit to other LSI SandForce based drives with 120GB. In my opinion, the best MLC SandForce based drive is still the OCZ Vertex 3 Max IOPS with 3xnm Toggle, as you can see there is a wide margin in sequential single queue depth read performance. The 3.20 120GB is also much lower than the Kingston V300 120GB, a new product that uses Toshiba 19nm Toggle flash.
We observed the same thing with the write performance. The 3.20 did very well at its peak, but the low and average results were down quite a bit compared to most everything else on the chart.
HD Tach - Sequential Write Performance after Random Writes
In this test the drive is no longer is a FOB state because we've written a significant portion of the drive with random data. This test also uses 128K blocks, HD Tune Pro runs 64K blocks. You can see on this graph that used blocks only make a small portion of the drive since the SandForce architecture compresses data before it hits the flash.
That means you tell the drive to write a fixed amount of data, but the controller doesn't pass all that data long as you transmitted it. As you know, when NAND has data residing on the flash it slows so this method keeps the SSD running faster for a longer period of time.
