Power supply underpowered for Rockpro64, deficient PCIe SATA card, or something else?

[t4_4t]

As you can see from the numerous reports, PINE's SATA-Card is not of good quality.
(I do not say that all products are of low quality, but it seems that there are many problematic products with "SATA-Card: ASM1061")

Try limiting it to SATA-3(6.0GBPS) -> SATA-2(3.0GBPS).

I have multiple "SATA-Card: ASM1061", but they have many errors similar to the one you pointed out, and I couldn't get normal operation without the above settings.
(* There is no error in the read operation, and at first glance it seems that it is working correctly, but when I perform a large number of write operations, an error occurs)

---
* PCIE-GEN2(5.0G)/GEN1(2.5G) and SATA-3(6.0G)/SATA-2(3.0G)

If the target is an HDD, any of the above settings will have little effect on performance.
In the case of PINE's "SATA-Card", it is effective to set a slower speed setting to get a lot of margin.

(The same board as PINE's SATA-Card is also sold on Amazon.
Therefore, I think that this Card is not designed by PINE itself, but sells some OEM products.)
