The ASUS MAXIMUS Z690 HERO has a large array of USB3.2 Gen2 USB ports. As of this moment, I am still sourcing USB 3.2 Gen2x2 enclosures for testing so I have to forego testing on that port as well as Thunderbolt4. We do test the Intel 2.5GbE and USB3.2 Gen2 headers on this board.
We test the throughput of the primary I/O of our tested motherboard using various devices as follows:
M.2 NVMe: KLEVV CRAS 920 2TB
USB 3.2 Gen2: ROG STRIX Arion USB Enclosure + Kingston KC2000 1TB M.2 SSD
SATA: SAMSUNG 870 QVO 1TB
LAN: QNAP TS-932PX 10GbE NAS + WD Blue SSD 1TB x2 RAID0
All tests are done in Crystal DiskMark v8.
NOTE: These charts do not show data in decreasing/increasing values.
These are all the slots on this motherboard for M.2. We did not include the ROG Hyper M.2 card in this testing.
