Performance is crucial for me. Please suggest any SSD in that price range(Rs. 7000 max).
Yeah, if performance is the key then nothing is better than Samsung 850 series. Next in line would be SanDisk Extreme. But in that budget you know how much storage you are going to get.
Thanks for the inputs. I would be only keeping the OS and a couple of programs so 120GB is more than sufficient. Everything else will go the backup drive.
+1 to Samsung Evo 850 ssd.
It would have been good if OP specified that how much memory is required.
