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 accesses.
HD Video Record
Trace writes an 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 (aprrox 1.2GB). It tests how the NAS deals with a multitude of small files.
The HD video scores from Intel's NASPT shows the benefits brought by the latest Intel Celeron processor and the
dual channel memory support. The HD Video Record test brings 100MB/s + performance across all arrays but once
again the performance dips when in RAID 6 mode for the other three tests.
When it comes to dealing with everyday workloads the AS6104T handles them without too much difficulty. It also shows pretty good consistency across the range when it comes to the multi file/file type Content Creation test and when faced with opening multiple small files in the Photo test. Once again the exception is when the device is using four 4TB disks in a RAID 6 array.
Great review sir! I noticed back at the end of Jan / early Feb 2016, the AS6104T as well as the AS6204T dropped in price, over 100EUR. I had my eye on the AS5104T for a while. Do you have any opinion if the AS6104T is better? Mainly because its even cheaper than the AS5104T now. The obvious difference is that the AS6104T supports 4k HDMI (which my current TV doesn’t support).
Thanks!
