User manual for WDS250G1B0A

I am interested in downloading a copy of the user manual for my SSD. However, in navigating through the links, I get to this:
I am not sure if this is the one for my drive because my drive is Western Digital Blue WDS250G1B0A and that user manual is titled “WD Blue 3D Nand Sata SSD.”

Edit: I see that this is the correct manual. On the second to last page, of the manual that I linked to, there is a list of drives, with model number that this user manual covers.

Yep, that’s the correct manual. Your model number is listed on Page 16.
