Storage Performance

The BIOSTAR X670E VALKYRIE has plenty of 10 Gb/s USB 3.2 Type-A ports, thanks to the dual X670 chipset(s). Knowing what devices are connected to what internally is a bit tricky, since BIOSTAR does not have a block diagram included in the manual. Therefore, educated guesses were made based on other motherboards layouts and possible configurations.

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

AIDA64 (SATA 6 Gb/s)

AIDA64 (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. 1035 MB/s is peak bandwidth for a USB 3.2 Gen2 2x1 (10 Gbps) enclosures.

AIDA64 (NVMe M.2)

Using a Gen4 x4 M.2 drive, testing shows that all M.2 sockets are at least Gen4 x4. Without access to a Gen5 NVMe, that M.2 slot cannot be fully tested. The M.2 Gen5 sockets are always connected to the CPU directly, no matter the motherboard as the X670 chipset does not have the throughput available for Gen5 devices. Interestingly, we can see an oddity in the charts. BIOSTAR breaks away from the norm with speeds about 1 GB/s higher than expected for the drives connected to the X670 chipset. It has been re-tested, so the results are accurate. Just not sure how BIOSTAR has pulled this off.
