You'll need find a different 2.5" SSD than the one you have selected. Your systems SATA port runs at SATA I (1.5 Gb/s) I/O speed. The Samsung drive you have linked to is a fixed SATA II (3.0 Gb/s) which is too fast for your system. The newer Samsung 850 EVO drive would be a better choice as it offers SATA speed sense technology which will match your systems SATA port speed.

There are a few other SSD drives out there that will work as well. Just make sure you check the spec sheets SATA Interface line that is shows SATA I (1.5 Gb/s) as workable.
I would also recommend before you alter things make sure your systems firmware is up to date. Follow this Apple T/N: About EFI and SMC firmware updates for Intel-based Mac computers.
