It has been a problem with all Microsoft Surface devices that somehow the OS takes a lot of storage space leaving users with a lot less then what they payed for. A lot less meaning not even half the storage space even if prices for the 64 GB variants go higher then usual.
As is the case with the Surface RT, the upcoming product from Microsoft named the Surface Pro is set to offer a complete experience in terms of running full desktop apps that are usually available for desktop PCs. Given that advantage storage space is a most for most users and the more the better. But what if the OS decided to unjustifiably take a lot of space. On PCs and laptops the Windows OS usually takes 2 to 4 GB of space, depending on the version and over time expands to reach sizes of even 20 GB. That is why it is recommended that you wipe and re-install Windows from time to time. But what in case of the Surface Pro.
On the upcoming Surface Pro the 64 GB version only leaves users with 23 GB of usable storage space. The rest is allocated to the OS in several ways. For one there is the virtual memory allocation that is recommended to be set at about twice the RAM. That means it can go for as high as 8 GB in storage space. Next there is the OS. Now Windows 8 might not take that much space but installing software can increase its size exponentially. Cause of this scenario we suppose Microsoft decided to allocate (a lot of) storage space to the OS. This brings us to the 23 GB of space that the user is left with. These need to surface for media and software and maybe some games as the Intel Core i5 can take a lot of it.
If you are concerned that 23 GB may not be enough think of it this way. Microsoft wanted to ensure a close to perfect experience running the OS without the problems users had to face with older versions of the system. Due process some sacrifices had to be made and several GB of space got “lost”. That does not mean the Surface Pro should be considered less than a great product. Besides you can always use a card for increasing storage space.
