Excellent. The biggest obstacle ive had to using Pis for practical things is that the memory cards eventually go bad. Looking forward to seeing this in the main release.
Eventually sounds like far far away In reality, they really have short lifespan, are slow, and halt the system Therefore I wouldn’t recommend the rpi anymore.

Couple more things to remember: - don't use swap - make sure you have noatime on all your filesystems - identify other folders with frequently changing data (/tmp, $HOME/tmp, etc.) and also make sure you keep them in memory - you can use NFS for many of these things if that is possible
Something I never understand: Why is this not the default? So many people struggle with the same stuff over and over again, yet, there's no mechanism in Linux distros to package default settings for a use case.
What they ought to do is put an easy way to set that in `raspi-config`
Re: I'm booting my Raspberry Pi 4 from a USB SSD
#23Does anyone know if its theoretically possible to run a cluster of Pi's off of the same external ssd at the same time? I'd like for say 4 Pi's to get a speed boost of not running off microSD, but I also don't want to shell out for 4 separate hard drives. I've looked in the past and have only found links to partitioning the drive so that it could be used when moving from one pi to another. But nothing about using it c…

Ideally the next Pi gets some interface that allows more integrated storage, like eMMC or NVMe, but even with USB the speed and durability justifies annoying cabling situations.

#25Really great article and very helpful, but where does the 8x faster for writes come from? I make it 6.2x.

Oops! My math must've been a bit broken. I'll update that part.

After swapping out the SD card with a new one, it appears to be fixed. This was hard to diagnose as there was nothing in system logs / error messages about what might have went wrong.

the lifespan is mostly due to writes, right? so couldn't you just boot from an SD card but save your actual data on an external drive?
Even if it does wear out, storing all the data on NFS (or a usb drive) makes it a lot less worrying.

Thanks! I tried to leave a comment on the article itself but it said I was blacklisted (first time visitor so I think something might be going wrong there).
