2TB SSD for a MacBook Pro late 2013

Hi, I am running out of space in my MacBook Pro (Retina, 15-inch, Late 2013) and I wanna buy a 2Tb SSD.

I see on Amazon the Samsung 850 Pro 2 TB 2.5-Inch SATA III Internal SSD (Model Number is MZ-7KE2T0BW) that could be perfect for me.

I looked at the photos and the Samsung dimensions seems different than the one now installed.

Might someone kindly tell me if this SSD is 100% compatible with my laptop? I can't understand.
