Both are Gen5 drives that the PS5 runs at Gen4 speed, so neither is good value for a console alone. If you are buying one anyway for a Gen5 PC, pick on heatsink fit and today's price rather than the headline speed. Today the 9100 Pro is £7.50/TB cheaper. The cheapest 2TB-class listings we found on 21 October 2026 were £225.00/TB (WD_BLACK SN8100) and £217.50/TB (9100 Pro).
