Notes
All NAS servers are tested using a single Ethernet link and are connected to our AMD Ryzen-based client via an Asus XG-C100C 10GBase-T PCIe Adapter and Qnap QSW-1208-8C 10GbE switch.
There are myriad ways of testing a network server, and with so many potential variables at play, we choose to keep things relatively simple with just a single client connected to the NAS. Drives are always configured as either RAID 1 on a dual-bay NAS or RAID 10 on a NAS with four or more bays, using the EXT4 file system.
