SSD Testing Methodology

Solid State Drives have traveled a long winding course to finally get where they are today. Up to this point in technology, there have been several key differences separating Solid State Drives from magnetic rotational Hard Disk Drives. While the DRAM-based buffer size on desktop HDDs has recently reached 64 MB and is ever-increasing, there is still a hefty delay in the initial response time. This is one key area in which flash-based Solid State Drives continually dominates because they lack moving parts to "get up to speed".

However the benefits inherent to SSDs have traditionally fallen off once the throughput begins, even though data reads or writes are executed at a high constant rate whereas the HDD tapers off in performance. This makes the average transaction speed of a SSD comparable to the data burst rate mentioned in HDD tests, albeit usually lower than the HDD's speed.

Comparing a Solid State Disk to a standard Hard Disk Drives is always relative; even if you're comparing the fastest rotational spindle speeds. One is going to be many times faster in response (SSDs), while the other is usually going to have higher throughput bandwidth (HDDs). Additionally, there are certain factors which can affect the results of a test which we do our best to avoid.

SSD Testing Disclaimer

Early on in our SSD coverage, Benchmark Reviews published an article which detailed Solid State Drive Benchmark Performance Testing. The research and discussion that went into producing that article changed the way we now test SSD products. Our previous perceptions of this technology were lost on one particular difference: the wear leveling algorithm that makes data a moving target. Without conclusive linear bandwidth testing or some other method of total-capacity testing, our previous performance results were rough estimates at best.

Our test results were obtained after each SSD had been prepared using DISKPART or Sanitary Erase tools. As a word of caution, applications such as these offer immediate but temporary restoration of original 'pristine' performance levels. In our tests, we discovered that the maximum performance results (charted) would decay as subsequent tests were performed. SSDs attached to TRIM enabled Operating Systems will benefit from continuously refreshed performance, whereas older O/S's will require a garbage collection (GC) tool to avoid 'dirty NAND' performance degradation.

It's critically important to understand that no software for the Microsoft Windows platform can accurately measure SSD performance in a comparable fashion. Synthetic benchmark tools such as HD Tach and PCMark are helpful indicators, but should not be considered the ultimate determining factor. That factor should be measured in actual user experience of real-world applications. Benchmark Reviews includes both bandwidth benchmarks and application speed tests to present a conclusive measurement of product performance.

Test System

  • Motherboard: ASUS P8P67 EVO (Intel P67 Sandy Bridge Platform, B3 Stepping)
  • Processor: Intel Core i7-2600K 3.4 GHz Quad-Core CPU
  • System Memory: 4GB Dual-Channel DDR3 1600MHz CL6-6-6-18
  • SATA 6Gb/s Storage HBA: Integrated Intel P67 Controller
    • AHCI mode - Intel Rapid Storage Technology Driver 10.1.0.1008
  • SATA 3Gb/s Storage HBA: Integrated Intel P67 Controller
    • AHCI mode - Intel Rapid Storage Technology Driver 10.1.0.1008
  • Operating System: Microsoft Windows 7 Ultimate Edition 64-Bit with Service Pack 1

Storage Hardware Tested

The following storage hardware has been used in our benchmark performance testing, and may be included in portions of this article:

Test Tools

  • AS SSD Benchmark 1.6.4067.34354: Multi-purpose speed and operational performance test
  • ATTO Disk Benchmark 2.46: Spot-tests static file size chunks for basic I/O bandwidth
  • CrystalDiskMark 3.0.1a by Crystal Dew World: Sequential speed benchmark spot-tests various file size chunks
  • Iometer 1.1.0 (built 08-Nov-2010) by Intel Corporation: Tests IOPS performance and I/O response time
  • Lavalys EVEREST Ultimate Edition 5.50: Disk Benchmark component tests linear read and write bandwidth speeds
  • Futuremark PCMark Vantage 1.02: HDD Benchmark Suite tests real-world drive performance

Test Results Disclaimer

This article utilizes benchmark software tools to produce operational IOPS performance and bandwidth speed results. Each test was conducted in a specific fashion, and repeated for all products. These test results are not comparable to any other benchmark application, neither on this website or another, regardless of similar IOPS or MB/s terminology in the scores. The test results in this project are only intended to be compared to the other test results conducted in identical fashion for this article.

# TCG OPALtcgopal 2011-09-08 12:53
I suspect the review wrong about this drive supporting the TCG OPAL specification.

Sandforce webpages claim it is an option, but I am not aware of any currently available Sandforce based SSD that actually supports it.

The drive webpage (##edgetechcorp.com/) makes no mention of TCG Opal.

ATA password != TCG Opal

Unfortunately after being burnt by a GTX460 review, a GTX460 that was supplied by the manufacturer for the review, and was a different spec to the released version I will take this one line very seriously:

Full Disclosure: The product sample used in this article has been provided by EDGE Tech.

But thanks for including it.

That is very unfortunate, which is why we disclose the source of our samples in every article. Almost every sample we receive is identical to full retail, but occasionally there are changes made to the retail product without any notice given.
