I’ve recently installed OpenWrt on a Raspberry Pi and would like to optimise it as much as possible.
My Raspberry Pi uses an inexpensive micro SD card. I’d like to get a better card but I’m wondering which qualities to look for. Some SD cards advertise themselves as having high read/write speeds, the marketing around others suggests they are engineered for long lives.
Which kind of primary disk (in this case the SD card) is it more important for a router to have and why?
My understanding is that most of the information is held in RAM anyway, and since there is 8Gb and only 10 devices it seems unlikely that it will every need to use the swap-space. So should I opt for the long-life disks (if that’s not just marketing) or should I go for the faster one? I’m not worried about the cost.
