In a PS5 both clear Sony's speed recommendation and load games alike, so the Crucial P310 wins on the things that differ: a heatsink version that is known to fit the bay. Buy the WD Blue SN5100 instead if it is clearly cheaper per terabyte today. Today the WD Blue SN5100 is £1.65/TB cheaper. The cheapest 2TB-class listings we found on 21 October 2026 were £115.00/TB (P310) and £113.35/TB (WD Blue SN5100).
