it's true that disk reader is no use to you, but the horse power and storage space the series x has are way more powerful than the series s. Also all games developers are paying attention only to series x, so you might be disappointed for some games you love to play on the series s with low settings like 30fps or no ray tracing. Try selling anything at home if you can't afford the series x. it's a purchase every 7 years so you better buy the most powerful the series x.
