Storage Performance

The EVGA Z790 CLASSIFIED includes six 10 Gbps Type-A ports. This should be enough for a majority of users that are just looking for any USB ports, regardless of the rated speed. These are good for headphones, USB Audio DACs, web cameras, game controllers, keyboards and mice. Those who are looking for more have access to the 10 GbE LAN and two USB4 40 Gbps Type-C ports as well.

*ORICO USB4 NVMe Enclosure (ORICO-M208C3-U4) used for USB bandwidth tests.

DiskSpd (SATA 6 Gb/s)

DiskSpd (USB 3.2)

The external USB-C enclosure is rated for 40 Gb/s over USB4 or Thunderbolt 3/4. The fallback is 10 Gb/s for everything else. 837 MB/s is about 150 MB/s lower than peak bandwidth using USB 3.2 Gen 2 (10 Gbps) enclosures. Unfortunately, the external drive stopped working part way through testing. USB4 was unable to be tested at this time.

DiskSpd (NVMe M.2)

The bandwidth of these M.2 sockets is in line with whats typical of these Gen 4 NVMe drives. A peak of 7 GB/s has been observed on other motherboards, and it looks like EVGA is a bit lower in that respect. Nothing that concerning, over 6 GB/s speeds are still quite impressive.
