Adding 2.5" ssd

[cvele]

I have Expertbook B1500CEAE.
I bought additional SSD to add it. Now I need to find out what I need to buy to do that, I know I need some kind of caddy or bracket and a flex cable, but I'm not sure which one is the right one and what terms to search online.

You can refer to page 34 of the service manual for instructions.
Thank you.

I bought 2.5" SSD to add it, not replace the M.2. Sorry for the confusion.

There isn't enough space inside this laptop for you to install a 2.5" SSD. 
You can consider purchasing a 2.5" SSD enclosure for use.

Thank you.
