so im planning to buy 128gb intel 600p to replace my slow 1tb hard drive as boot drive, but when i check whether my laptop m.2 support nvme or not, i found out that it does but only in pcie x2. i was wondering will this impact or affect the speed much as the ssd is not so fast at speed of under 1GB/s? if you are wondering what my laptop is, its acer e5-475g-53iq(kaby lake), correct me if im wrong about something i said here. note: the reason why i dont look up on the m.2 850 evo is mainly because slightly more expensive price and its slower, but feel free to suggest another ssd at price of somewhere nearby the 600p
