I have an HP ProBook 450 G5 with Intel i7-8550u. It has an NVME slot, but nowhere I can find if it's gen3x2 or gen3x4. I need to know because I want to know if it's worth to buy an NVME or just SATA SSD.
The HP manual doesn't state it: http://h10032.www1.hp.com/ctg/Manual/c05695301. It only says "512 GB, PCIe, NVMe, TLC" - Does that also mean that it only supports up to 512 of NVME drive and not 1TB? And only TLC type and not MLC or QLC?
