What is the Number of this SSD board R

@wistam - Why did you take the logic board out of its case?

You do realize each SSD maker does their own thing and I don't know of any maker posting schematics or board views of their products to even tell you what the missing component is.

It also might not be missing at all! Just because you see solder pads does not mean the placement was populated. Is the SSD not working? The best I can offer you is to see if you can get a warranty replacement form the maker of the SSD.
