System Speed Test Benchmarks

EDITORS NOTE: Please read Solid State Drive (SSD) Benchmark Performance Testing to understand how the benchmarks used in this article should be interpreted.

It's show time! All claims to performance are either made real or proven false in our testing, and although SSD's clearly offer some advantages it sometimes takes seeing a product compared to the performance of others to prove the point. Not very long ago I decided to take action and get System Speed Test v4.78 back in our test rotation. This software is solid, and the results are more accurate than any others available that I have used.

I doubt that when DOS died, Vladimir Afanasiev ever thought he would see his System Speed Test software used again in professional reviews. This program offers comprehensive system information, but it also has a powerful benchmarking tool for memory, processor, and disks. In terms of disk performance, it measures interface and physical transfer rates, seek and access times at the hardware level, and it does so without delay or interference from Operating System software or running processes. This is why Benchmark Reviews will continue to use this test: it polls its results directly from the hardware without the need for Windows!

To detect the Random Access Time of each device, we ran full test routines on all products a total of five times. The highest and lowest scores were ignored, and the remainder was averaged. This would be pointless however, because in every single access time benchmark the test results were identical. In the bandwidth tests the results were extremely close to the others, and therefore required averaging.


To my complete surprise, System Speed Test access time benchmarks places the Mtron Pro 7500 SSD at the very top of our results. With a lightning-fast 0.08 ms access time, every other SSD is forced to live in the shadow that the MSP-SATA7525 has just created. The sub-0.1ms group of top performers also includes the MemoRight GT, Mtron Pro 7000, and Mtron MOBI 3000. Clearly, Mtron knows a little something about keeping random access time to a bare minimum in their Solid State Drives. The OCZ SATA-II OCZSSD2-1S64G, Samsung MCCOE64G5MPP, Silicon Power SATA-II SP032GBSSD750S25, Patriot Warp PE128GS25SSDR and original OCZ OCZSSD64GB maintain the midrange level or random access times between 0.14ms and 0.23ms.

At the slower end of our SSD response time chart is the original SATA Silicon Power SP064GBSSD25SV10, OCZ Core Series, Crucial's CT32GBFAB0, and the Super Talent MasterDrive MX finishing out the list. In reality you couldn't begin to perceive these subtle differences, but technology should get better with time and not the other way around. It's also worth keeping in mind that our Hard Disk Drive alternatives are a much slower to react: Western Digital's Raptor took 8.53ms to respond, followed by 12.99ms for the Seagate 7200.11, and 15.39ms for the 7200 RPM (most are 4800 RPM) Hitachi Travelstar 7K100 notebook drive.

Bandwidth is a whole other consideration once you record the results. In our tests, both the Western Digital Raptor and Seagate 7200.11 Hard Disk Drives showed strength as only a select few SSD's could meet or exceed their buffered read performance. A larger 32MB buffer in the 7200.11 makes a 7200 RPM HDD difficult to keep pace with, and the 10,000 RPM spindle speed offer enough of an advantage to keep the Raptor on top. Close on the Raptors' tail was the OCZ OCZSSD2-1S32G and OCZSSD2-1S64G, which is based off of the Samsung MCCOE64G5MPP-0VA SSD which performed the same. The Seagate 7200.11 HDD was nearly matched in buffered read bandwidth by the Super Talent FTM60GK25H and Patriot Warp, with the Mtron Pro 7500 a short distance behind marking the end our our high-bandwidth finishers.


Leading the midrange portion of our SSD group was the SATA-II Silicon Power SP032GBSSD750S25 which performed almost identically to the older SP064GBSSD25SV10 SSD. The Crucial/Lexar CT32GBFAB0 trailed close behind, while the OCZ's CORE SSD performed at the same level as the Crucial/Lexar SATA-II SSD, while the OCZ Core Series SSD, Mtron Pro 700, and Mtron MOBI 3000 complete the midrange list. The low-end portion of our drive performance chart is occupied by the original OCZ SSD, which lasted mere minutes on the market after being released early 2008.

Looked at a different way, and ignoring the dominant buffered read speed results trend set by the Hard Disk Drives, the top SSD's actually did well to hold ground against the Raptor and 7200.11, which are at the very top-end of HDD performance.

Disk Hardware Tested:

  • Crucial / Lexar 32GB 2.5" SATA-2 SSD CT32GBFAB0
  • Hitachi Travelstar 7K100 2.5" 60GB SATA 7,200 RPM HDD HTS721060G9SA00
  • Samsung 64GB 2.5" SATA-2 SSD MCCOE64G5MPP-0VA
  • Seagate 7200.11 500GB 3.5" ST3500320AS 7,200 RPM SATA-II Hard Disk Drive (32MB Cache Buffer)
  • Western Digital Raptor 74GB 3.5" WD740ADFD 10,000 RPM SATA Hard Disk Drive (16MB Cache Buffer)
  • Although Benchmark Reviews completely endorses the test results of System Speed Test for our benchmarking, it's always good to have other sources. We decided to then test our collection of SSD products using the HD Tach RW and ATTO Disk Benchmark tool in the following sections. Please continue to see if our results were a fluke or not.
