My old laptop still was usable, but battery was not just unhealthy, but also starting to fail with the laptop not detecting it has a battery inside very frequently, so it was time to do something about it. But even if I decided to replace the battery, the limitations of the laptop wouldn't let a fully compatible and healthy battery last more than 4 hours of use, which would be way too risky for taking it to university for a full day, so I ended up getting a new laptop.
It's a HP laptop, it was going through a double discount so I got it for much cheaper than what it usually costs and it was the best option I had for this price that wasn't a chromebook. It comes with windows 11 and I decided to give it a try; maybe some open source tools like openshell can make it less painful to use? ... yeah no, 2 days of use and it's the most frustrating experience I've ever had with a computer, no wonder sometimes the windows 10 marketshare rises while w11's drops. So yeah, linux time! Did some research and everything should be fully supported out-of-the-box as long as I'm using the kernel 6.4 or newer (that means no debian because it uses the 6.1, but at least Zorin meets the requirement with the 6.5)
My worry is the warranty, as this is still too new to know if it has any problems or not, and since previous questions about this in HP forums haven't given a clear answer (some say installing linux doesn't void the warranty but some say that it does...) I don't want to format nor partition the SSD yet. So that's where the SD card comes in.
I'm aware of the speed limitations of SD cards and I don't mind, as this is a temporary workaround that wouldn't be in use for more than 1 month, since it is more about testing things like battery life, CPU temperatures at light but long sessions of usage and on idle, something a live USB would struggle a bit more with, since, at least on windows, battery lasts for around 10 hours, and I don't think it's a good idea to keep a live session running for that long.
So my question is: Would running a linux system from a SD card for light usage on long sessions from time to time during a month affect significally the health of a 256 GB SD card or should it be fine? I would love being able to use that SD card in my nintendo switch after this, as the 64 GB it has is starting to run a bit short on storage.
