Thinking about the expandable SSD storage again today....man it would be really wise to wait for a hardware revision and a larger on-board SSD if you can. 825 GB is simply not enough. Plus those aftermarket expandable models are going to cost nearly half as much again as the PS5 system, and that's just for 1 TB. Seems like most people are going to have to get by with the stock SSD space; that's just too much money to spend.
We're entering the $800 range. That's before any games or extra controllers. Storage space is where the manufacturers reallllllly skimped this time around. Of course they did it to save on costs but it's still a very poor value proposition to consumers.
For people whom don't know, during the past one year costs have not come down even a single cent on PCIe 3.0 and 4.0 NVMe drives. They were cheapest shortly after last black Friday, went up before Christmas, and then remained at that premium from January forward. All while under numerous industry insider reports last year that "flash memory prices are crashing, there is a huge oversupply; the price of SSDs will be coming down". That never happened, and that was well before the pandemic hit.
Don't count on those prices getting cheaper. We're also talking about super-premium SSDs that don't even exist for sale right now with 5,500 mbs speeds. I have trouble imagining that the system is going to require only 5.0+ speeds. The two previous gens of stuff haven't gotten cheaper at all and these won't either. Not for the first couple of years at least.
