You can buy Samsung 850 Evo 500GB for around 150$ / € and many people do.
Might seem like a lot, but I'd buy one and install in my PS4, except it has SATA II so there's no point.

I would never dream of buying a 500GB SSD for a current gen console. Way too small. The SSD part doesn't make that any better.
