The memory card reliability really emphasises the limitations surrounding save files on the platform.
My 64GB card died about a year and a half after I got mine in 2016. Lost all my saves since the last backup a long time before. I regret going digital for most of my Vita games because of how the save files are tied to the game files.
Deleting a game means losing your save unless you back up the entire game (but then restoring entire 1-3GB games massively increases the writes done to the card) or subscribe to PS Plus full time.
I’m back on a 16GB card with only a small fraction of my library on it, but I did end up rebuying a few games boxed. I’m more annoyed about losing something like a couple of hundred hours of progress across my games though.
