A:AnswerThe external hard drive could work for it. I do believe that you may have to reformat it for it to work but I’m unsure. There are USB-C ports in the front and back and there is a USB-A port in the back which most likely would connect to an external Hard drive used for a PS4.
A:AnswerThe difference primarily is that the Regular Playstation 5 has a disc drive and the Playstation 5 digital edition does not have one, which is why theres such a price difference between the two.
If you were to get a Playstation 5 Slim Digital, you would be able to buy a disc drive from Playstation and add it in the future if you'd like to, but that is not a possibility with the original PS5 digital
A:AnswerI would reccomend the ps5 slim disc edition, due to its great amount of storage, 200 gb more than original, and new look. Since the ps5 original is 3 years older than the ps5 slim anf ps5 slim digital, I personally reccomend the ps5 slim disc eddition.
