SSD for Arma

I am thinking of buying another SSD, I already have a 120 GB one that acts as my boot drive and I have all of my vital programs on their such as chrome, discord etc and it has no more storage left at all. I don't particularly want to spend more than 70 pound and don't want an M.2 drive either just something that is really good for price per performance and something that will mainly increase loading times on games like Arma 3.

Honestly you dont know what your missing out on with playing Arma 3 on a SSD cos with the HDD it was slow loading but with a SSD you dont need to let stuff load in 90%-99% of the time it will keep up with you depending on your specs but obs with HDD you have to let it load in before doing anything majority of the time
