Hello my girlfriend is now using a hdd on laptop but she had an SSD drive but it is now dead. So I am looking for a powerfull storage unit and especially NVMe. She is working in autocad, archicad and so.. and some projects she is opening lasts a few minutes, even on SSD. And her laptop is a i5 8th gen and gtx 1050. So I wonder if the NVMe opens a program with project much faster than SSD (if its worth), and if a laptop can run only on nvme without hdd or ssd in it plugged.
