I’ll buy another new SD card because I already flashed it before because of such a login problem so I guess my SD card is corrupted.
Do you have a recommendation for an appropriate one ? will 16GB is enough for HA ?
If you look at this wikipedia page, the two tables below my link, you’ll see the speed classes and application classes. The first link you have, the speed class is 10 (in a circle). That means that it’s good for 10 MB/s. The one I linked has a speed class of 3 (inside of a U), which means it’s good for 30 MB/s. It’s a bit confusing, I know.
32GB or larger is recommended, so I would just go for a 64GB one if that’s the smallest you can find.
Yes. An A1 card will work, but is more likely to die early and have other problems.
An A2 type card is able to handle 266% more read IOPS, and (more importantly) 400% more write IOPS. It’s a card type optimized for running applications that have many small I/O operations like HA does.
A 16GB A1 card will work, but why deviate from the recommendation?
Another question : I’m looking for a safe way to shutdown the RPI (hass.io installed on) other than pulling its power from its power connector. How can I do it ? maybe this what cause my sd card to be corrupted.
