Just wanted to ask what everyones experience has been with using microSD cards as the system drives for your RPIs. I am building a custom rpi4 as a network controller, but its going to be installed somewhere where it will be very difficult to reach and replace the sd. I am by no means an expert, but all it is doing is basic firewall tasks, so there shouldn't be much written data, just reads. I am using a 16gb sandisk ultra microSD.
Thanks in advance!
p.s. I know that EMMC is the superior option when it comes to storage longevity but an emmc module wont fit in my custom enclosure, and im pretty sure a microsd card should be fine, just wanted to double check.
