NAS Storage Performance Benchmarks
Atto Disk Benchmark
One of the more common tools available to measure storage performance is ATTO. It is very reliable and produces accurate results. The great thing about ATTO is that we can test with predefined block sizes. So we can test with a sequence of 4 KB files up-to 1 MB files. This gives us a pretty good overview of overall performance with small and large files in a queue.
We've seen this in the past with RAID configurations as well, write performance on these NAS units have a hard time remaining close to the 2.5 GiGE marker, this is related to the SoC from Realtek, apparantly it cannot keep up with 2.5 GiGE performance even in reads.
