Hi, I am tasked with testing several NAS HDDs connected to a Ubuntu Host. I am being asked to run performance tests with fio. Besides the how to document, can you share any documentation for maximizing video file performance? In particular, where can I get more information about IO engines? Which engine to use for NAS systems when measuring video file performance? What is the relationship between the parameters size and runtime? Does runtime become redundant when we specify the size?
