Intel NAS Performance Toolkit
Intel NASPT is another disk sub-system test that employs 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’s NASPT seems to provide a more adequate picture of SSD performance, in our opinion. And we see the same things as in PCMark 7, but bigger now. The Toshiba THNSNH actually wins this test, outperforming not only the OCZ Vector and the Plextor M5 Pro but also the seemingly invincible Samsung 840 Pro. Obviously, the Toshiba THNSNH is a very good SSD for desktop and mobile PCs that run everyday applications.
Besides the average benchmark score, we would also like to offer you the results of individual usage scenarios, which will show where new Toshiba SSD can really shine. Note that the data-transfer rate is higher than the SATA 3 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.
Judging by the results of specific usage scenarios, the Toshiba is just blameless. It copes easily with typical desktop loads, so Toshiba’s optimizations hit the target precisely. Even though the resulting product doesn’t look good in synthetic benchmarks and at server loads, it’s perfect for everyday applications.
