I think I'm not going to use the full Read speed since games don't use the full.
For example, GTA V max loading speed is less than 3200Mbps an NVME can reach.
The 250GB SSD + 1TB SSD cost me total a total 273€
A 1TB NVME cost 330€+ and i think at the moment i will not use all the speed NVME have to offer.
(I'm new in M.2 SSD's so i don't know that much)
