What is the best budget SSD right now?

Hey guys i'm looking for a good SSD. I used to have a Crucial MX100 256GB that served me well. I gave that one to my mother and picked up a Trion 150 480GB. While it works, I have noticed it hiccups once in a while. Something my MX100 never did. Now I picked up the Trion before any credible reviews were published. It was cheap though, real cheap.

So what I am looking for is a new SSD around the 500GB mark. I do have a bootable M.2 slot if you know of a good alternative.

Based on my own research, it appears the Sandisk Extreme Pro 480GB is the top of the budget range right now @ $195 USD on Amazon.

Anybody have an opinion on this? Is the Extreme Pro still top dog in the budget category?
 


Is the 850 EVO or Extreme Pro not reliable? I haven't heard of any unusually high failure rates on them other than the thing with the EVO which I assume was corrected with a firmware update.
