The worth of an SSD upgrade mostly boils down to which games you play. It's a winner for a Bloodborne fan, where the cumulative time spent looking at loading screens can certainly add up by the end - and every saving helps. But for titles where quick restarts are on hand (such as Metal Gear Solid 5), the value of an SSD upgrade is lessened somewhat. But even here, we do shave seconds off the clock when booting into a mission, almost halving the process of a stock drive.
To put these stats into perspective, loading times across all six games tally up to 15 minutes and 50 seconds on a stock PS4 drive. By comparison, an SSD jumps through all the very same hoops in just 11 minutes, 10 seconds overall. The savings on a solid state drive can't be questioned here, but the idea of cumulative gains is an interesting one - an upgrade that means we cut 28.6 per cent of the wait across a breadth of titles in our library. The length and frequency of loading times varies per game, but it's something that clearly tallies up over the course of a year.
