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 is not as favorable towards the SSDNow V+200 120GB as PCMark 7: the Kingston is almost 7% slower than the Corsair Force 3 and 41% slower than the Corsair Force GT. The Kingston SSDNow V+200 is not a typical SandForce-based product with asynchronous memory, after all. It is not equivalent to such SSDs as Corsair Force 3, OCZ Agility 3, Patriot Pyro, etc.
The detailed INASPT results help us see what usage scenarios are the most suitable for our today’s testing participants. Take 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.
The way the SSDNow V+200 120GB compares to a typical SSD with SF-2281 controller and asynchronous flash depends on the particular application and load. The difference can be negligible, for example when copying files and folders from the SSD, installing software or exporting photos. But there are also scenarios when the SSDNow V+200 is really slower than the Corsair Force 3: compilation of large programming projects, copying folders to the SSD, archiving and video transcoding.
