Suggest SSD - Budget 4k

[beingGamer]

Hi all I want to buy an SSD. I have about ~3500Rs at hand which i got by selling the unwanted WD green.
I want to use them to buy a SSD, can anyone suggest which one to go for?

Samsung 840 EVO 120GB's price is 5050 on FK, is it the best price? or should I try local stores?
Also what is the usable disk space?
