Which SSD is better to insert into an old laptop: ASUS X42F (Pentium P6100 2GHz)?

Question

ASUS

There is an old laptop: ASUS X42F (Pentium P6100 2GHz / 6GB DDR-3 / SATA-II)
It is planned to use it for a couple of years, so I would like to speed it up.
I'm going to put an SSD drive up to 256 GB , the price is not higher than 6 thousand rubles.
What do you recommend? What to foresee? What pitfalls can be?
ps: for the time being I chose Kingston A400 [SA400S37 / 240G] 240 GB, for 5.5 thousand with a three-year warranty - maybe something is wrong with it?

Answer 1

Samsung 850 Evo 250Gb is the de facto standard. The absolute leader in the entire budget segment

Answer 2

Any, from a normal manufacturer.
The model you specified is the correct solution.

What to foresee? What pitfalls can be?

Yes, there are no special problems, put it in and it works.
The only point is that the old laptop may not have AHCI support, so TRIM will not work and you may encounter speed degradation. To solve this problem, it is enough to leave part of the disk unallocated.
The SATA version has no effect.
