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 so pessimistic about the Petrol. Yes, the latter takes last place in the diagram, but it is not much different from the Kingston SSDNow V+200 which we found in our previous review to be the slowest among SandForce-based SSDs with asynchronous memory.
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.
It is easy to discern a pattern in the Petrol’s behavior. This SSD is lackluster when processing a lot of small files, but accelerates on large files. Thus, it is inferior to SandForce-based SSDs with asynchronous flash in such tasks as archiving, folder management, games, photo management, data search, and launching of the OS and applications. On the other hand, the Petrol is fast at copying large files, installing software and working with videos, and even occasionally outperforms the Corsair Force GT Series that is equipped with synchronous NAND flash.
