Yet for computers it was

1KB = 2^10 bytes
1MB = 2^10 KB or 2^20 bytes
1GB = 2^10 MB or 2^30 bytes
1TB =  2^10 GB or 2^40 bytes

Computers are base 2, not base 10.

It all went wrong with the internet though, as well as marketing for HDDs. Those are base 10 instead of base 2.

I'm throughly confused, where does the "extra" data come from with GiB if a bit is always a bit... does it start at the byte? How is the byte different that you end up with 24 extra gigs? I might be too tired for this one. Are they the exact same size but GiB has inflated numbers that aren't real? Can someone explain this to me like I'm addicted to Clair Obscur and I'm loosing chunks of sleep to play that game.  🙃  please.

Is the polling options accurate to the storage on a launch PS5 at 667.7 GB? 

There is no extra data, it's just a marketing ploy.

Computers work in bits, on or off.

1 byte is 8 bits
RGB color is 3 bytes or 24 bits color

1 KB is 1,024 bytes (2^10)
1 MB is 1,024 KB
1 GB is 1,024 MB
And so on.

Now instead of selling a 1 TB drive as containing 2^40 bytes, which is 1,099,511,627,776 bytes, HDDs get away with 1,000,000,000,000 bytes and call it a TB. Converted back to computer GB or GiB, that's 931 GiB.

It's the same with your internet connection advertising in Mbps.
100 Mbps in computer terms would be 104,857,600 bits per second or 13,107,200 bytes per second (divide by 8), 12.5 MiB per second. (divide by 1024*1024) Instead you get 11.92 GiB per second. Not only do they make it seem bigger by advertising in bits, also using the decimal system.

Thus 825 GB is equivalent to 768.3 GiB 

Now it all depends on whether the advertised file size is in GB or GiB.



Anyway memory still uses the correct measurements, if you buy 32 GB RAM, you get 32 * 2^30 bytes, or 32 GiB.
Any other storage you buy uses base 10 nowadays. A 32 GB USB stick is only 29.8 GiB. (I've hit that problem before, why won't this file fit...)
It's just that computers work with a base 2 RAM bus, 256 bit RAM bus, which does not allow going base 10 with RAM as well. RAM needs to stay addressable in base 2, can't cut corners there.

Oh, Yeah I see. Well if my math is right the OS should be around 65gb. You'd think it would be 150gb at first them 83 gb but it's actually no bigger than 70gb. That's wild, real head fuckery stuff. Surprised this is legal. 

Edit: No wait. It is 83gb no...? Oh fuck me. Ai can't think right now, I'm too tired. 

It's mostly reserved storage space for system downloads and video recording. The system always needs to keep space for an hour of gameplay video at max quality so you can use that at any time.

I wish Apple did that as every month my wife curses her phone out again with the next Apple update. Free up 12GB, delete a couple thousand pictures...

That's true for sequential read speeds, but regarding random IOPS and even sequential writes, UFS 3.1 storage is more comparable to a SATA SSD than even a modest NVMe like that Xbox Series one.

The NVMe standard consumes way more power than UFS, so yeah, no surprise in these results.

I'm awake and fresh minded. While I understand exactly the deal between GB and GiB I don't understand how SSD manufacturers and Sony are using this to manipulate the data on the drive. I need to know exactly the size of the OS or it's going to drive me bonkers. There is ZERO data online and I can't figure it out. Can someone please help, in standard GB that are used by games.

My PS5 Pro reports a 1.89 TB SSD, just to add to the confusion.

2 TB = 1.82 TiB = 1,863 GiB = 1,907,349 MiB = 1,953,125,000 KiB.

1.89 TiB = 2.078 TB.

It also says 132.8 GB reserved for System storage. (And that it depends on how the system is used)


I don't know what standard GB is used by games lol,

My biggest installed game is GT7, 138 GB, smallest Akka Arrh 131.7 MB, but no way to tell if that's GB or GiB. I assume it matches what's used for storage and at least it reports the same amount in storage as in properties on the dash board.

Oh ffs. And it's different on the slim than the launch model too. Oh that's so aggravating, that's all so aggrevating. I seen from the article someone posted above that there were class actions about this, for good reason too. This is an issue where you standardise like USB and everyone gets on board for that standardisation, USB-c happened in an easy flash, this shouldn't be so hard to sort out, it's not their mistake but it's their mistake that they aren't fixing it for accurate numbers on the box. 

Edit: There is an "oother" section on the storage that seems to shift size, maybe that's it. Something that holds data from apps or when you install an app in reserves data in "other" or something like keeping a YouTube video buffered when the app is closed. 

And rest mode of course. Suspending a game means temporarily storing the contents in RAM to SSD, another 12-13 GB to reserve.


I disabled hibernation on my laptop to free up precious space on my system drive, which is only a 256 GB SSD. With 32GB RAM hibernation would take up over 10% of my system drive. (Hyberfil.sys)

There's still around 5GB in pagefile.sys, using the SSD for extra RAM (something consoles don't deal with) which I don't get why Windows still insists on needing when I rarely exceed 12GB RAM in use out of 32GB (I upgraded RAM for FS2020, now never use the extra 16GB) but there's still 1.3GB in the paged pool according to task manager.

Anyway Windows reports 4864 MB allocated for the pagefile, Total Commander reports pagefile.sys at 5,100,274,664 bytes = 4,864 MiB. So here Microsoft is using the computer version of MB, not the base 10 version.

Windows also says my SSD is 237 GB, which much be 237 GiB = 254,476,812,288 bytes.
Total Commander reports my drive as 248,882,172 k = 254,855,344,128 bytes. (close enough with rounding, this is 237.35 GiB)

For my 1TB storage drive Windows claims 931 GB, Total Commander 976,760,828 k (931.5 GiB / 1.000 TB)

So it seems Windows is using GiB and TiB. What does Series X use...


Maybe it's all in the 'correct' form on devices, it's just marketing that's using base 10.
