Is 500GB of Hard Drive Space For Next-Gen Consoles (Xbox One, PlayStation 4) Enough?

For anyone who has a current generation console (PS3,Xbox 360), 500GB of hard drive space sounds like a lot. Most gamers are content with their present 80GB of hard drive space. But few have considered that the next generation console's games would eat there present console's hard drive space for breakfast. No wait breakfast is too big of a meal, let me rephrase, the next-gen console's games would eat your present console's hard drive space for brunch. Yeah brunch sounds more accurate. A PS4 game like Knack takes 37GB of  hard drive space when it is all said and done. Call of Duty: ghost takes up somewhere in the 45GB range. So when it all said and done, you might have maybe 12 games saved on your Next-Generation console. But that would only be the case if you had all 500GB of space to dictate to only your games. A part of any hard drive spaces goes to the system's operating system. So for the Xbox One you have 362GB of usable hard drive space, which equals about 8 games that you can have saved on your system. For the PlayStation 4 you have 408GB of usable hard drive space, which is a little better than the Xbox One, but it only equals about 9 games that you can have saved on your console. I think hardcore games can max out that much of available hard drive space in 6 months to a year, with causal players not far behind. In the beginning it might not be that hard to manage you available space but through the lifetime of your console, it is going to suck to only have 8 to 9 of your favorite games saved on your console. which will bring gamers to the inevitable, switching out their stock hard drives for a bigger one. while I talk about why the PlayStation 4 is special to women games in this link here , it is because of how easy it is for anyone (tech skills or not) to do the dirty deed of switching out the hard drive. For the Xbox One I know it is a lot more difficult and not so initiative, but if you want more information on how to get to the hard drive on the Xbox One checkout  this link here, it will take you to Geek.com where they go over some of hardships of getting to that elusive hard drive on the Xbox One. Now with the Xbox One and PlayStation 4 increasing digital game sales by 25% in only a month, this issues of hard drive space really needs to start getting some attention. You don't want to wait too long to switch out your hard drive because of the data you will lose, but you don't want to switch it out too early because it will void your warranty. I'm hoping that game developers can find a better way of utilizing the power that is available on both the Xbox One and PlayStation 4 without killing my hard drive space in the future. And that Xbox's One and PlayStation's 4 figure out ways to use cloud computing to alleviate some of the crazy amount of hard drive space next-gen-games require.
