500GB Samsung 850 EVO no longer available

I was disappointed when tweaking my build early this weak to find that the 500GB Samsung 850 EVO isn't available any longer. I feel like this is a massive goof on DS's part. It is one of the most poplular, if not THE most popular SSD ever. I emailed them, and they said that it may or may not come back and that there is no ETA on a replacement. I was hoping they would have the new 860 version up within the last few days to replace it but, alas, it is not so.

That having been said, my question is whether I should wait and see if they repost it or possibly the new 860, or if I should go with the 500GB M.2 SATA drive instead. According to the configurator, it would be a WD Blue model, which is well reviewed. Does anybody have any experience with the WD Blue M.2 drives? The prices are nearly the same, and so is the performance. However, I really hate to settle, but I realize that I could be waiting forever, so I may have to.

Also, getting one of the bigger EVO drives available is out of the the question. They are way too expensive for my budget.

Here's a link to my build just in case: https://www.digitalstorm.com/configurator.asp?id=1836484

Well first comparing m.2 with sata(850) is apples and oranges.

Also i recommend going with the pro version, for better reliability and warranty.

Samsung is king in ssd right now and i would stick with them, if wd blue m.2 is anything like blue hdd, i would stay away from it anyway.

My advice to you for best chance at least headache is to go 850 pro or 960 pro just keep in mind as mentioned 860 should be out soon so if you are going 850, wait for 860 to come out, that is probably why DS is out of stock.
