The case for 4TB
The PS5 has a single M.2 slot, so you cannot add a second drive later. If you expect to outgrow 2TB, buying 4TB once is cheaper than buying 2TB and then replacing it. Today the cheapest compatible 4TB drive is £107.50/TB.
The case against
If the price per terabyte at 4TB is clearly above 2TB, you are paying a premium for space you may never fill. A cheap external drive can archive games you are not playing for far less.
