Question Custom Firmware for Realtek RTL9210B-CG (UnionSine MD202) – Need Guidance

[ghardkeys]

Hello everyone,
I’m looking for help regarding a custom firmware for my UnionSine MD202 SSD External Case , which uses a Realtek RTL9210B-CG controller. I’ve attached a screenshot from the firmware update tool (UTHSB_MPTool_Lite) to provide more details about the device.
Here are the specifics:

• Device Model: UnionSine MD202
• Controller: Realtek RTL9210B-CG
• Firmware Version: 1.29.12
• Build Date: 2022.01.11
• Manufacturer: Realtek
• Product: RTL9210B-CG

I’m interested in a custom firmware to potentially improve performance of this SSD. I’ve tried searching for resources online, but I couldn’t register on Station-Drivers to ask my questions there, so I’m hoping to find some guidance here.

Is the firmware at this address compatible with my external SSD enclosure: https://www.station-drivers.com/ind...oller-firmware-version-1-33-98-090324?start=0
