However, SD2Vita is a recommended improvement, as it offers players the possibility to expand the amount of external storage space they can use to play at a lower cost. The technology also gives players the freedom to explore more games and, overall, makes the gaming experience exciting. It's not worth buying unless you plan to play games from 10 years ago. Don't get me wrong, it was a great system, but nothing new from Sony in many years means it's not worth buying.
This is no longer a problem, because if you do something like softmod with Ensō and install an SD2vita in the game's cart slot, I think you can reach 256 GB.
