Thanks, also edited the ini file and updated my Pluggable USB-NVME to 2.09. Performance is down slightly less compared to the original 2.04 firmware perhaps even margin of error on my USB 3.1 GEN 1 (max 500mb/s) port. I updated prior it to Yeji 2.08 firmware from on an earlier wonderful post here and saw the same margin of error less perf.
IOW... Updating from the original 2.04 Pluggable firmware to 2.08 Yeji firmware, the performance is margin of error less. 2.04 to 2.09 firmware, it's the same margin of error less. I didn't compare 2.08 to 2.09. I seriously doubt it's anything significant.
I am glad I was able to change the name and serial number of my Pluggable back to the original. The 2.08 Yeji renamed it to Yeji with serial # ~9876543210. I doubt this thing is in warranty anymore after this. I'll chime in again if I encounter any issues.
After applying the firmware you can edit the EEPROM variables (drive name,etc) without reapplying the firmware, you can also have it try to use the HDD serial number and name, but didn't work for me.
