I would use the Samsung 850 evo 500gb. The cost is similar to the sandisk, but I think it is a better device.
Really, all modern ssd's perform similarly in normal desktop operations. The value of the Samsung pro is increased longevity, not performance.
I have used both and can't tell the difference.
A pro might last 15 years to the evo 10. It is a moot point, both will be obsolete long before they wear out.
