Intel’s NASPT (NAS Performance Toolkit ) is a benchmark tool designed to enable direct measurement of home network-attached storage (NAS) performance. NASPT uses a set of real world workload traces (high definition video playback and recording, video rendering/content creation and office productivity) gathered from typical digital home applications to emulate the behaviour of an actual application.

We’ve used some of the video and office apps results to highlight a NAS device’s performance.:

• HD Video Playback: This trace represents the playback of a 1.3GB HD video file at 720p using Windows Media Player. The files are accessed sequentially with 256kB user-level reads.
• 4x HD Playback: This trace is built from four copies of the Video Playback test with around 11% sequential access.
• HD Video Record: Trace writes a 720p MPEG-2 video file to the NAS. The single 1.6GB file is written sequentially using 256kB accesses.
• HD Playback and Record: Tests the NAS with simultaneous reads and writes of a 1GB HD Video file in the 720p format.
• Content Creation: This trace simulates the creation of a video file using both video and photo editing software using a mix of file types and sizes. 90% of the operations are writes to the NAS with around 40% of these being sequential.
• Office Productivity: A trace of typical workday operations. 2.8GB of data made up of 600 files of varying lengths is divided equally between read and writes. 80% of the accesses are sequential.
• Photo Album: This simulates the opening and viewing of 169 photos (approx 1.2GB). It tests how the NAS deals with a multitude of small files.

In the video tests of Intel’s NASPT benchmark, the TS-364 showed strong performance breaking the the100MB/s mark for all tests, with the fastest performance, 278MB/s, coming from the HD Video Record test trace while the drives were in a RAID 0 array.

In the office tests, the NAS displayed strong performance with a pretty good level of consistency across the tested arrays. The best performance came in the Office Productivity test where it averaged 77.1MB/s for the three arrays. When dealing with the multitude of small files that make up the Photo Album test it averaged 58.1MB/s while in the Content Creation test it averaged 19.73MB/s.
