Why xbox series s and not x even I can afford it

Games is 30% lower space but same quality

It's not the same quality. It will still look good though. No doubt when you're playing a Series S on 1080P TV or a monitor it will look great, it won't look as good on a 4K TV.

SSD is like same write cycle as Series X

Tech spec wise the internal SSD is the same, but not size wise. The Series S has a 512GB drive while X has a 1TB

The expansion SSD cost a lot

It does, but even with slightly smaller games, you'll still need the Expansion SSD at some point.

It had built in scaler that up scales 4k with no loss image quality

It does, but it's not the same as playing in native 4K. You won't notice image quality differences too much on a 1080P TV or a 1440P monitor, but side by side it will be pretty clear.

It plays all games on account instead of discs like 80 games

It's a digital only console. If you already have an Xbox One with a large library on disc, the Series S isn't really meant for you as you would have to buy your games again. If your library is digital, then S maybe the right choice.

Hdr is not but standard like lutbox and TV is quite bright

I'm really not sure what you mean by that statement. Both versions of the console support HDR, but your TV needs to support it to.

It target minimum 60fps you can't see faster you only get more details when moving fast like car games in 120fps but same graphics. There isn't really a minimum for either console. There may well be some 30fps titles still. However, I foresee
60 fps being far more 'the norm' this time around. The great thing is, you'll still get 60 fps in most if not nearly all games on Series S.

As for 120 FPS, it's a little more complicated than that. It's true, 'you can't see faster', but motion on screen is a lot smoother. All games benefit from faster FPS, especially First person shooters. However, 120FPS is very demanding and will force many
games to be both rendered in lower resolutions and have some graphics settings toned down. This is how Dirt 5 gets to 120 FPS.

Let's discus why I should get series x instead

I broke your last statement into two parts. Really only you can make this decision.

Series X

• 2X larger Internal storage than Series S
• A Blu-ray Drive for disc games from the Series X, Xbox One and the BC 360 and original games. It will also play Blu-ray movies, UHD Blu-ray movies and DVD discs.
• Much more powerful graphics hardware for up-to Native 4K resolution and higher resolution assets.

But, even if you buy a Series S, you could still upgrade to a Series X later. All you'll need is your Microsoft account. All of your digital purchases will be available on the Series X still, plus you'll be be able to install games from disc.

It's up to you and your own budget/needs.

It should be on there. But if not ? You can wait for the xbox x series or the xbox series S (the more affordable one )

What the original Xbox one? It’s good but if you can afford it then get the newer series s or x if you got the cash

because you can set the console to 1440p and 120hz.

but the S is very underpowered and is primarily a 1080p gaming machine, it has less power than the xbox one x and it is already showing that it is aging badly, lots of games running at subpar graphics and framerates.

most games don't even hit 120 fps.

series x even struggles to hit 120fps in some games.

All in all the Xbox Series S was made for those that are casual gamers, those that 1080p is ok, those that cannot afford the series x etc etc.

If we can have gift cards that know when they've been scanned then why can't we have discs that know when they've been scanned? Or just make the game tied to your Xbox Account just like the digital version is. When someone installs a game with a disc, have it be the same as if you purchased it through the Microsoft Store. It honestly would not be that difficult. Or at the VERY LEAST offer an attachment that is a disc drive. This isn't really the most affordable console ever released. I bought my Xbox One Brand new for $300 and paid $250 for my Xbox Series S on Black Friday. I can already give my disc to someone else and let them play it on the other consoles. Hell you can do it with the Xbox Series X. So why is it such a big deal for the Xbox Series S? Not everyone can afford to buy the digital copies of all their previously bought disc games. Not everyone can afford to pay $700 for the Xbox Series X.
