Solutions exist but cannot be buyed by individuals like me because we don't make a business
So, you're saying that you can't afford a mechanical hard disk? Or that only businesses have the scale to be able to attach a drive in a caddy?
Not that I can't, but won't: Want to keep everything in the small enclosure & low power (a HDD does not).
Now, being able through Farnell of reselling some industrial uSD (MLC with good WL algos, or some pSLC ones that offer endurance 10 times MLC one, with only doubling cost per bit): That's in the 25 to 50€ range for a 16GB depending on underlying NAND techno. A bit more than consumer grade devices but worth it.
That's just a question of making these industrial devices, that exists, available to individuals that take benefit of RPI low power needs for 24/7 application.
If providing a USB port on IO pinouts is so expensive to allow eUSB (not even speaking of M.2/Sata, I gave several options in my first post), one solution exist with no HW cost for those who don't need it.
Some says buying an oversized consumer grade SD for your needs will provide better endurance: It's not true, or marginal, as dynamic wear leveling create hot-spots on the fraction of the device that is often written (i.e. log files vs OS/program ones). Doing so is just wasting money vs the right sized device with adequate specs.
You can minimize writes, but not making everything read-only to keep a usable device (+some level of logs to understand problems post-mortem), that's only going from half a year before problems occurs to a full one or so. So still a major problem for these kinds of neds
