is it good to buy used m.2 ssd

[nvincent_08]

i just get a new laptop at december last year, i wanna buy the one with m.2 ssd equipped, but as it is really hard to get that laptop with pre installed windows(which im looking for) and because my old laptop hdd is dying, so i necessarily bought that laptop, after around 1 month usage, i feel the laptop is really slow and hanging right after boot up sometimes, which probably because my laptop use 5400rpm hdd and have bunch of data in it, so i decided to get a ssd as it is supported, but the problem is some couple weeks ago i see a m.2 128gb ssd at around $45(converted price) and it suddenly disappear from online store that i usually shop at, yesterday i saw some used m.2 128gb ssd at around $33 with mixed brand, some of them is sk hynix, samsung, micron. cheapest m.2 128gb ssd that i could get for new is around $56 and the brand is team. could someone pls help me which one is the best option?

Your laptop motherboard needs to have an M.2 slot, does it have one? I've never seen a laptop with one.

1. I would not buy a 128GB drive for the OS. No matter what type it is. That is right on the edge of too small these days.
Just yesterday, we had to work with a guy who had a 120GB drive. The OS and a single game on it, and he was running out of space. The game took up ~55GB.

2. I would not buy a used drive, unless it were under $10
