I upgrade my mom's 850 EVO M.2 to a 960 EVO M.2; both 500GB. You can't go wrong with either, but when I read in a PC Perspective story that they booted into Windows 10 in ten seconds and six seconds respectively, I just had
to go for the 960.
By the way, after I bought the 960 EVO 1 TB last night, the price jumped from $429.99 to $479.99. However, the $479.99 price now has a savings promo code that deducts $60 from the price. My purchase did not come with the deal. Very interesting.
Anyway, watch this.
