Hi. I have a Dell Laptop and I want to upgrade my SSD. Currently, it only has 128GB SSD which is basically nothing. My m.2 slot support SATA and PCIE SSDs. I've been looking at the Samsung 970 Series and the Samsung 860 Series. I would like a 500GB SSD as I think that should be more than enough. On my laptop, I do a lot of programming, light productivity use, light photo and video editing, and a lot of multitasking. First off, should I get the Samsung 970 Series or the 860 Series? And then, which specific SSD from that series should I get (Evo, Evo Plus, etc.)? Thanks in advanced.
