IMHO best M.2 NVMe SSD in Q1 2018, but since it's an OEM drive Samsung offers literately no drivers if you buy one of them aftermarket (which I tried), so gotta wait for the "980 evo" or whatever they'll call the non OEM version... [Mar '18 GreyGoose]


If you have the PCI-E lanes to support it... This is hilariously potent. Read/writes out of this world, that only workstations would ever truly find useful, if even that. For games, you'll never worry about load times again. [Aug '19 xDEFCONx]
