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 seems to provide a more adequate picture of SSD performance and the SandForce-based products aren’t so incredibly fast here. However, we can see that the customized firmware helps the Intel 520 and the Kingston SSDNow V300 perform faster than the others. The SSDNow V300 is only slower than the recognized leaders in the diagram, so it turns out to be the fastest SF-2281 based solution available from Kingston right now.
Besides the average benchmark score, we would also like to offer you the results of individual usage scenarios, which will show where Kingston SSDNow V300 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.
The SF-2281 controller isn’t new, yet it’s not outdated yet. It can often rival other platforms in real-life applications, especially when there’s a lot of random-address reading to be done. That’s why a SandForce-based SSD is quite a good solution even today.
Compared to similar offers from other brands, the Kingston SSDNow V300 is a very good choice. It is just faster than common SandForce-based SSDs with 24nm or 25nm synchronous flash. In fact, it is only inferior to the Intel 520 which is bolstered by its customized firmware.
