In 2017 and 2020, respectively, the author reported on his research on qualitative and quantitative performance evaluation of relatively low-cost Network Attached Storage. This report is a continuation of the 2020 report, in which the NIC of Synology's FS6400 all-flash storage was replaced with a 40Gigabit Ethernet NIC, and a 100Gigabit Ethernet Switch was used to connect the 100Gigabit Ethernet NIC to a Linux server. From a Linux server with a 100Gigabit Ethernet NIC connected by a 100Gigabit Ethernet Switch, I prepared multiple values with multiple parameters using the I/O test tool fio, and conducted exhaustive measurements to benchmark all combinations of these values. The measurement results were formatted and visualized in a heat map. This time, I applied this method to disk arrays with a unit price of 100 USD/TB terabytes, all-flash storage with a price of 250 USD/TB, and all-flash storage with a price of 5000 USD/TB.
