Yeah when you look at games like The Witcher which can take upwards of 70GB and the fact that the PS4 system files consume about 20-40GB of the drive... ontop of the fact that in a 500GB SSD you're actually going to have 465GB since the number writen on the box is always based in Bytes and it's 1024 of those per KB and 1024 of those per MB and another 1024 of those per GB so yeah I mean you're looking at being able to install maybe 7-10 AAA games on a 500GB drive or closer to 5 games like The Witcher.

Sorry but another small correciton needs to be done here.

The space of an HDD is calculated by using a Standard Base 10 system so that every KilobByte is calculated as 1000 Bytes, whereas a logial KilboByte is calculated using a base 2 system and is actualy 1024Bytes.

So as you go up each factor the disparity is larger and larger. For exmaple a 1 TB drive actually nets you 931 GB instead of 1024 GB which is a real Terabyte.

What correction is that? Or Correciton?

I pointed out that a 500GB drive will give 465GB, you work out that a 1TB drive will be 931GB, Double the stated amount in my post for a 500GB Drive, just wondering what aspect of my post you thought you were "Correciting"?

The correction was on the terminology and incomplete explanation that you used. The part that comprised the corrected statement was only in my first paragraph. The second paragraph was just, as I thought a simpler example to highlight the disparity. 

Your statement bolded above does not correctly explain why there is a difference between the advertised Drive capacity and the logical (or as I had typo’d, logial) capacity. You do properly explain the how logical base 2 storage is calculated but failed to explain why that differs from what is advertised by the HDD manufacturer.

In short my correction was really just adding why there is a difference by explaining both sides.
