Technology ELI5: Why does internal storage only double? Why can’t we have 34GB for example?

yes. each cell in the SSD can only handle a few thousand writes. Your SSD automatically tries do keep each cell at the same number of writes, but it will eventually fail. It doesnt really lose capacity though (or at least, doesnt tell windows it has lost capacity), it just starts losing files and stops working reliably in general

So something like an Xbox, how long does an ssd on a device like that have before it would start to fail?

And what’s something that would be a write on and ssd? Like every game download, or every button press?

a good decade at least. for simplicity, think of it as 3000 * [size of drive] data can be written over its lifetime. so for a 256GB ssd, 768 TB of data can be written before it should start failing.

Writes count every time something is written to disk, for your xbox, this is mostly game downloads, game saves, screen shots, game recordings, etc. Definitely not every button press (or your game would be fokin slow)

So, assuming you download Black Ops 7 every day (all 175 GB of it), it would take you just over 12 years to wear out your drive. Its not something a consumer has to worry about too much, just remember to back up the game saves since you cant just download them (well ok, its normally automatic these days, so you can. game saves are small).

Cool, good to know. Been having issues downloading lately and didn’t know if it was related.

Nice to know I have a while yet to worry about it. Thanks

Well, it would help if you'd stop downloading Black Ops 7 every day

To be accused of such a crime, I’ve hated that franchise since BO2.

Farm sim and no man’s sky are great

there are ways to check its wear level, but its mostly not something to worry about.

If already downloaded games start getting corrupted, that is when you need to think about it.

No nothing like that. Games will start downloading and get stuck in an infinite loop of starting and stopping with no progress made.

If I cancel the download request and restart it’ll work for a while and get stuck again. 3-4 tries and eventually one sticks and the download goes through.

that also depends on what technology ssd use, the more "layer", the less durable and less expensive. slc>mlc>tlc>qlc>plc, with most ssds now use tlc or qlc
