Does speed really matters in SSD ?

So , I was searcing to buy an SSD for my lenovo laptop(i5-9300H GTX 1050) and I found that there are cheap one with like 500 m/s speed up to 7000m/s ..

The price is almost 5 times in my country , so does it really matters ? Regarding the size of the ssd.

Is this a good one for normal usage and some 2K gaming :
