Need sata cable for X415EA_X1400EA

[JBL121]

I want to install  a 2.5" sata drive in my Vivobook X415EA_X1400EA. I read there is an A and B connector.

Which one do I need. I dont want to order one and find out I needed the other.

Thanks

You can install a SATA III, 7mm, 1TB hard drive.
Thank you.

I have the HD but need to order the sata connector cable. There seems to be 2 types, A and B.

I need to know which one to order.

Thank you for any responses.
