Unless your running some very disk intense stuff or like to run benchmarks I doubt you will see a difference.
After the warranty runs out ask yourself if you need a TB of storage space.
If the answer is no then consider a simple one 500GB ssd setup.
I'm looking at buying this computer. They offer it with different disk drive options. According to the item's description SATA maxes out at 550 MB/s while the NVMe maxes out at 3,200 MB/s. So is it worth the extra money? I plan on replacing the HDD with an SSD eventually. Does that matter?
