There is nothing wrong with knowing that you need to get something more to make sure you are getting the maximum out of your console. Sometimes we think that a console is an object that should give us exactly what we want, when we want it. But consoles are not upgraded in that sense. When you have gotten a console with a certain amount of hard drive space, you cannot exactly go in two years later and say you want a replacement console with a bigger hard drive. You have to make do with what you have.
But what you can do is take some other steps to ensure you get that hard drive space you want for all the big games that you are buying and playing on the PS4. So take a look at the best HDD for PS4 that is available for less than $100. These are the same external hard drives that you would use on your computer, but they are the ones that are going to properly work with your console. Do not make the mistake of buying a generic external drive without checking whether it works with your console or not.
The great thing about these externals is that they practically give you double the space that you had before with your console. Say you got a 500 GB console, and now you are able to add a 500 GB or a 1 TB external drive. Now you have double or triple the space that you did before, and you will never have to worry about having to delete a game that can no longer fit on the hard drive space that is on your PS4. Having an external drive takes your console gaming experience to an entirely new level and that is what we all want.
