So the BEST consumer SSD to me is the SAMSUNG 950 pro M.2, I got it and is nothing short but amazing!
Also SanDisk Sata3 SSDs are great!
Remember if you want to have a quality one, go for a MLC NAND tipe (check the specs), if you want more space and spend less money go for a TLC NAND
Intel by the way are very good as well, but for me, their prices are for business solutions only!
