A Samsung SSD, top!
I've only used Samsung SSDs since their 840 series. I've used 840s, 860s, 870s, 960s and now 990s. They have always been top-notch, reliable and are controlled via Samsung MAGICIAN. It's a real plus to have just one brand to be able to centralise everything. What's more, Samsung allows you to manage over-provisioning to increase the already excellent lifespan, as well as Clone functions to migrate your old system to your new drive.
So I've got this drive as a dedicated drive for games, and it's clean.
