Hard drives maximum size is the largest capacity available in the market.  Your system should work fine with 8TB drive.  Be sure to initialize it with GPT during setup to access full capacity.
My system is: Dell XPS 8930 purchased in September 2019.Intel Core i7-9700 @ 3.00GHzInternal hard drive C Toshiba NVMe 512GBMemory 16GB DDR4 2666MHzWindows 10 Home Edition upgraded to Windows 11 Version 22H2. I added an extra internal hard drive (Seagate Barracuda 4tb) as Drive D for all data.This drive died a few days ago and I replaced it with another of same size and brand.However, I was wonder if I would have been able to install an 8TB ? What is the maximum size of hard drives I can install in XPS 8930 ? Thanks for your time.
