Storage & USB on the ASUS ROG Maximus Z890 Hero Motherboard
To test M.2 and USB speeds we make use of CrystalDiskMark hard drive benchmarking tool. Our first drive is the Crucial T705, which is a Gen5 or PCI-Express 5.0 drive.
The next drive we tested was the Patriot Viper VP4300 Lite. It is a Gen4 or PCI-Express 4.0 drive.
For USB testing we have the Lexar SL660 BLAZE, which is a USB 3.2 gen 2×2 drive. We used the Thunderbolt 4 Type-C port on the rear I/O of the board.
