HD Tune Pro Benchmarks

In the past, Benchmark Reviews has avoided HD Tune benchmarks because the software was so similar to others already being used in our articles. However, EFD Software has released several versions of the program, which add functionality and features with each revision. The latest edition of HD Tune Pro allows random access read and write testing, a feature not available to other software 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 for 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 random transfer size IOPS performance.

Benchmark Reviews has tested the Patriot Torqx 128GB MLC SSD PFZ128GS25SSDR against a collection of top-performance Solid State Drives for our random IOPS benchmarks. By nature, Single-Layer Cell (SLC) SSDs perform far better at delivering high operational transactions per second when compared to Multi-Layer Cell (MLC) products.

The Patriot Torqx, while being virtually identical to the OCZ Vertex SSD and Super Talent UltraDrive ME, share very similar architecture but very different IOPS performance. While Indilinx offers firmware updates on a frequent basis, OCZ appears to be ahead of Super Talent in terms of development, and despite this Super Talent is ahead of Patriot. One example is with TRIM technology, which resets sectors on the SSD as they are erased, thus restoring write-to performance to its pristine peak.

In the chart above, the OCZ Vertex EX enjoys the benefit of SLC construction, which delivers traditionally better IOPS performance. The OCZ Vertex (MLC) has the advantage of TRIM enhancements to the firmware, witht he Patriot Torqx and Super Talent UltraDrive ME showing signs of reduced write-to IOPS performance. Hopefully these two companies will address this issue with future firmware updates.

All of the above-mentioned SSDs appear to be well ahead of the OCZ Apex and G.Skill Titan SSDs, which utilize the dual JMicron controller in an internal RAID-0 array. The JMicron controller reveals its inherent weakness, producing miserably low single-digit IOPS performance. Even the much older SLC products, OCZ's OCZSSD2 and the Mtron MOBI 3000 or 3500, all perform better during write-to tests.
