An 8TB drive in a PS5 with 2TBs of internal storage already is expensive cold storage. You don't really even have to manage the storage on a 4TB drive anymore and can just be reckless with it. Considering how they rape you on 8TBs and we doing stuff like pay in 4 that doesn't seem like a good deal. You can get a 4TB for under $250 if you want and skip the external and have $450 or so left over.It's all about having immediate access. There's no waiting for a download or an upload. All which while can be fast enough these days, is still various amounts of minutes of time. I have a 4 TB in my PS5 currently and going to take that out and add it to the Pro so I'll have near 6 TBs of immediately accessible games. WATTBA, bish.
