Intel NAS Performance Toolkit
Intel NASPT is another disk sub-system test that uses real-life usage scenarios. Like PCMark 7, Intel NASPT reproduces predefined disk activity traces and measures how fast they are executed. However, the default traces are designed for network attached storage devices rather than for SSDs. Therefore during our test session we replace them with the specially developed SSD Benchmarking Suite which offers more relevant usage scenarios such as compressing and decompressing files, compiling large projects, copying files and folders, loading 3D game levels, installing software, batch-processing photos, searching a digital library for data, mass-launching applications, and transcoding video.
Like PCMark 7, this benchmark gives us a true-to-life illustration of disk subsystem performance. Here the SSDs are again tested in their “steady” state.
Intel NASPT offers a more adequate picture of real-life SSD performance, in our opinion, and it thinks that the OCZ Vector is even faster than the Plextor M5 Pro. Now we can be absolutely sure that OCZ has come up with one of the world’s fastest consumer-class SSD. Many remarkable products now look just mediocre compared to the OCZ Vector and the Plextor M5 Pro.
Besides the average benchmark score, we would also like to offer you the results of individual usage scenarios, which will show where OCZ Vector can really shine. Note that the data-transfer rate is higher than the SATA III interface bandwidth in some subtests. That’s because INASPT is a high-level test that uses standard Windows functions to access the disk subsystem. As a result, the OS caching mechanisms also affect the results.
It is all thanks to the technology for improving write performance which was first employed in the Vertex 4. Now, using the higher computing power of the new controller, it delivers even more impressive results with the Vector. The latter is one of the best SSDs in every scenario that requires high writing performance and also confidently good elsewhere. All in all, the Vector is suitable for any usage scenario.
