USB to SSD connect jetson nano

After I use a USB adapter card to convert an SSD into a USB interface, I connect it to the Jetson nano card. There are two problems in use.

  1. During reading and writing, the device will be kicked off. From the system, the drive letter of / dev / SDA cannot be seen. It cannot be recognized after reboot. You can only recognize the SSD after power down and power on again.
  2. The read-write performance is very unstable. The DD command is used to test the read-write performance. Sometimes the performance can only reach 30MB / s. when the environment remains unchanged, the performance can sometimes reach 160MB / s only after power on again.
    Excuse me, have you ever encountered these two problems?

Is this NV devkit or custom carrier board?

Do you have external power supply to this SSD? By default the power supply from jetson may be not sufficient.
