The 850 EVO M.2 SATA SSD is a good, cost-effective choice for budget systems. The 950 PRO M.2 NVMe SSDs and the new 960 PRO M.2 NVMe SSDs are better choices for performance systems.
Hope this helps,
I agree with the with the information send by Scott. Since I guess that you are living in Tel Aviv, my advice is to buy this SSD in local store (like KSP). It will cost you lest than ordering from Amazon: KSP מחשבים וסלולר and you will have local service.
