Storage Performance

The Gigabyte Z690 AORUS Tachyon is a PC enthusiast overclocking orientated product. As such, it is lacking high-speed USB 3.2 Gen2 ports. Essentially, only three 10 Gb/s ports are available, one of which is rated for 20 Gb/s. The rear I/O section is decent for those who don't need a bunch USB 3.2 20 Gb/s or Thunderbolt 4 ports.

AIDA64 (SATA 6 Gb/s)

AIDA64 (USB 3.2)

The external USB-C enclosure is only rated for 10 Gb/s; 1 GB/s is quite high compared to other motherboards I have benchmarked using the same M.2 USB 3.2 Gen2 2x1 (10 Gbps) enclosures.

AIDA64 (NVMe M.2)

Using a Gen4 x4 M.2 drive, testing shows that four M.2 sockets are indeed Gen4 x4 with the correct amount of bandwidth allocated to each socket.
