Like so many other memory vendors on the market, Kingston offers a wide array of solid-state disks for your perusal. For the low-end segment, it has the SSDNow V series, which at current time offer the best GB/$ on the market. We’re taking a look at the latest release here, combining a recent JMicron controller with Toshiba NAND.

Synthetic: SYSmark 2007 Preview

Synthetic benchmarks have typically been favored for performance testing, but the results they provide can be fairly abstract, and the methods they use to assign their scores can be dubious at times. By contrast, real-world application benchmarks provide performance metrics that apply directly to real-world usage, and we endeavor to apply both in our performance comparisons.

SYSmark 2007 Preview from BAPCO is a special case, because its synthetic scores are derived from tests in real-world applications. However, we still believe that synthetic benchmarking scores are best used to directly compare the performance of one piece of hardware to another, and not for developing an impression of real-world performance expectations. SYSmark is more useful than most synthetic benchmarking programs in our opinion, because its tests emulate tasks that people actually perform, in actual software programs that they are likely to use.

The benchmark is hands-free, using scripts to execute all of the real-world scenarios identically, such as video editing in Sony Vegas and image manipulation in Adobe Photoshop. At the conclusion of the suite of tests, five scores are delivered: an E-learning score, a Video Creation score, a Productivity score, and a 3D Performance score, as well as an aggregated ‘Overall’ score. These scores can still be fairly abstract, and are most useful for direct comparisons between test systems.

A quick note on methodology: SYSmark 2007 requires a clean install of Windows 7 64-bit to run optimally. Before any testing is conducted, the hard drive is first wiped clean, and then a fresh Windows installation is conducted, then lastly, the necessary hardware drivers are installed.

SYSmark’s exhaustive battery of recorded real-world usage tests is an important factor when trying to gauge drive performance. According to BAPCo, differences of 3 points in the final scoring should be considered meaningful. Given the age of this test suite, the “Preview” part of the benchmark’s name, however, is definitely not.

The Kingston V 425 Series drive falls in the middle of the pack here, delivering mixed results that allow it to finish in the middle of the pack. If there was any doubt about the JMicron controller though, then just look at the SiliconEdge Blue’s results at the top of the pack. Given the plethora of SSDs Kingston offers, they should consider licensing WD’s firmware or potentially investing in developing their own.

We are now fairly certain our test system is capping performance and hindering these drives from pulling away from each other in the individual tests. Even so it is clear that the traditional platter hard drive still has no hope of keeping up.
