HD Tune Pro Benchmarks

The latest edition of HD Tune Pro allows random access read and write testing, a feature not available to other similar software benchmark tools. HD-Tune is a low-level test that will not operate on a drive which contains a partition, so Benchmark Reviews uses DISKPART to prepare hardware and remove any partitions before conducting these tests.

Random Access tests are divided into 512b, 4KB, 64KB, 1MB and random size test files sizes. The Random Access test measures the performance of random read or write operations. The amount of data which will be read varies from 512 bytes to 1 MB. Performance is reported in operations per second (IOPS), average access time, and average speed. Because it is our intent to compare one product against another, Benchmark Reviews has focused on 4KB and random transfer size IOPS performance.


Benchmark Reviews tested the Corsair Nova V128 SSD against a collection of top-performing desktop storage drives for our IOPS benchmarks. The HD-Tune 4KB random operational performance measured 5690 (22.23 MB/s) read IOPS, and 15025 (58.69 MB/s) for maximum write performance. In comparison, the SATA 6Gb/s Marvell-based Crucial C300 offered 7941-IOPS (31 MBps) read and 2451 (9.6 MBps) write performance, while the Indilinx-based Corsair X256 scored 7444-IOPS (29.1 MBps) read and 16244 (63.5 MBps) write, whereas the Toshiba-based Kingston SSDNowV+ SNVP325 produced 4855-IOPS (19 MBps) read and 2583 (10.1 MBps) write.


The tight range of IO is an indicator of operational bottlenecks. For example, the WD VelociRaptor WD3000HLFS SATA Hard Disk Drive indicates a total top-to-bottom read-IOPS range of 10-150 whereas the average SSD might offer 200-10,000. As a direct result, in most cases SSDs will offer a much higher IO over their hard disk counterparts. The random read/write operations per second is charted below:


Our test results were obtained after each SSD had been prepared using the DISKPART program with the "clean all" command, and Indilinx-based SSDs received Sanitary Erase. In our tests we discovered that the maximum performance results (charted) would decay as subsequent tests were performed on the Windows 7 Operating System, even with TRIM available. As a word of caution, alignment and garbage collection applications offer immediate but temporary restoration of original 'pristine' performance levels.
