A:Answer Depending on your budget, I would recommend either the Samsung 970 Evo Plus 1TB or the Samsung 970 Pro 1TB. Keep in mind, the motherboard supports up to PCI Express 3.0. You can use a PCI Express 4.0 hard drive, however you won't be able to take advantage of the rated speed of that hard drive. Also, the motherboard on this model is inverted, so the hard drive will not be easily upgradable. You will want Geek Squad to perform this upgrade to ensure any warranty is not voided.
