Just before E3, Microsoft released a new version of the Xbox One with a 1 TB HDD to help the system gain an edge against Sony's Playstation 4. Now, Sony has taken this advantage away from the Xbox One by releasing a 1 TB model of the Playstation 4.
Every gamer knows that nowadays, video games take up a ton of space. Most AAA titles anymore would need four or more standard-sized DVDs just to hold the essentials, let alone any added DLC, so naturally the gaming industry has moved past DVDs as the primary medium for distributing video games.
Although Microsoft and Sony come with Blu-ray drives, and games are still sold in this fashion, a large number of gamers are now opting to just download games instead. With the adoption of these methods, the average size of a game has exploded and is virtually unlimited by storage size; that 500 GB HDD isn't going to hold out long before gamers max out its capacity.
If you are one to buy new games frequently and purchased one of these systems when they were new, it is very possible that you have already filled that HDD, then had to go through the hassle of deleting your older games to make space. Granted, it lets you install new games now, but then you have to wait for hours to re-download that game you deleted whenever you want to play it again.
In the end, although this might seem like just a marketing move to try to get more sales, it is actually a necessary move that Microsoft and Sony need to take. It may seem like a minor inconvenience, but when users have to mess around with their HDD to make space, it is bound to cost the companies sales.
Users won't want to deal with trying to decide what to delete, or might decide to do it later and simply forget. Again, I know these are small issues, but it doesn't take much to lose a sale, and by upgrading to 1 TB drives it ensures that users can go twice as long before the storage available becomes an issue, and for many, 1 TB will be all they ultimately need.
Unfortunately, for the time being the system is only available with the 1 TB HDD in Europe and certain PAL regions. However, a U.S. release is likely in the works, and a document by Sony has already been filed with the FCC for a 1 TB PS4. If you are looking forward to having a 1 TB PS4, then keep your eyes open because it shouldn't be long before you can get one.
