It also depends if the PS4 is your main system or not. I mostly buy exclusives for my PS4 and the multi-platform games for my PC. Therefore I need much longer to fill up the 500 GB as someone who buys exclusives + multi-platform games for his PS4.
Most PS+ games for PS4 (a.k.a. Indie games) are very small, I have dozens of them installed and they only use a fraction of the storage space.
