  • I’m not sure how this hasn’t been mentioned yet but a lot of the Midwest doesn’t like California because it feels like there’s a migration of californians who have been priced out of California moving into the Midwest who both bring their left leaning policies into right leaning areas and buy up so much property it drives housing even higher.


  • They both use entirely different technologies to store data. RAM is basically just a transistor and a capacitor used to store each bit. This makes it extremely fast to access but it requires a constant supply of power or that capacitor will just discharge. There really isn’t that much that can wear out using a capacitor and transistor so they have long lifespans.

    SSDs use NAND flash. Basically they trap some electrons in an insulated section (the gate of a floating gate MOSFET) and to read that they measure the electric field caused by those electrons. This wears out because sometimes electrons may unintentionally quantum tunnel into the insulated section and become permanently trapped there. And once enough electrons have become permanently trapped there, you can no longer distinguish between different values.

    You can’t use RAM technology in SSDs because it’s volatile - when power is removed all data gets wiped. It’s also much less dense than NAND flash. 1TB SSDs are pretty easy to find but when was the last time you saw a 1TB RAM stick at a reasonable price?


  • Messing up the serial configuration shouldn’t affect your SD card. SD cards typically run off SPI or SDIO whereas a serial port runs off a UART or a USB virtual comm port if the processor on the board supports that. They shouldn’t affect eachother.

    I would confirm your serial settings are correct, flash it using the SD card, then hook up your computer to its usb port and see if you can send/receive commands over a serial console. If you can see stuff you probably just misconfigured your display settings.

    Worst case you have to buy a $5 stlink off Amazon and flash it using JTAG which is guaranteed to work unless there’s some kind of physical damage
