I tried using a Pi4 for a pihole and it kept crashing. Overheating I think. But, if I solve that, the SD card would kill it eventually.

you can disable all logging in pihole - which i do and my sd card from 2016 is still going strong.

Not if you get a good SD card, or a USB SSD.

  When I was trying, boot from USB wasn't available.

What power supply were you using? My Pi 4 running 2 instances of Octoprint kept crashing until I switched to their official power supply. On previous models I always got away with whatever power supply I had around but the 4 doesn't play around when it comes to power consumption.

  The one it came with!

    I had to replace the one mine came with. It was new-ish, so I was able to get it for free under warranty, but be aware- quality control for their power supplies is not great (at least as of ~2017)

    I've had various Pi models over the years starting with the original and I've never gotten a power supply with it. You must have bought a bundle deal, which could mean a good or bad one depending on the seller..

I've had a bunch of Pi Zero W cameras in 24x7 use for years in a very harsh desert environment where ambient air temps regularly exceed 120F, and have never had a single crash of any of them, not even a failed SD card despite being written to daily for storing motion-activated images (the sunrise/sunset is always captured). I don't even have fans on these, and they're in the compact pi foundation red and white case for camera use. It's really been quite impressive. What I've heard is a crashing Pi is usually due to sagging voltage on an inadequate power supply, and that's probably even more an issue on the more demanding/powerful Pi4. On my cameras I just use the wall warts adafruit sells for the Pi, and haven't had any power problems.

  Again, I'm using the supply it shipped with. Not that having to use their supply because they screwed up the spec is an acceptable situation, mind you.

Be careful with the gear you use on your Pis, just like any system. If you’re using a no-name USB-C power supply and dirt cheap generic SDHC cards, you will likely have problems. By default, the Pi4 doesn’t come with a power supply and while you might be tempted to power it from your PC, spend the money for the official power brick, or, even better, get the official Pi Power over Ethernet hats. For SD, buy from a reputable source and get a brand name (Samsung or Sandisk). This is anecdata from my part, but I’ve got eight or 10 Pis running (Flightaware/ADSBexchange, PiHole/Influx/Grafana/Wireguard, a couple of Octoprint, Home Assistant - with a relay HAT for triggering dampers, Showmewebcam, and a handful of other things). Once I switched to good power supplies and good SDHC cards, my problems went away. My most heavily loaded machine is the PiHole machine which also has influx running and writing to the SDHC card - it’s probably a ticking time bomb, but it’ll celebrate it’s fourth birthday on the same card in two months.

  I walked into the Cambridge Raspberry Pi shop on launch day and bought a Pi 4, a power supply, and an SD card with NOOBS. It isn't my hardware that's at fault and, even if it was, it doesn't excuse developing hardware that doesn't work with in-spec USB-C power supplies and depends on inherently fragile storage media.

    I missed this -- but my comment elsewhere about the FW update for overheating definitely applies for a launch day Pi4!

As long as you use something like the official PSU and don't connect particularly power-hungry USB devices to it you should be fine. As far as the SD card goes you can boot off an external hard drive or SSD via USB and that should guarantee longevity. My biggest problem with headless Pis was that they would randomly disconnect from the wifi network and disappear, turning off power saving on wifi didn't solve it. In the end the real solution ended up being to just create a 2.4ghz-only network and connect them to that. Somehow they just don't play well with networks that have the same SSID for 2.4 and 5ghz on my Ubiquiti gear.

  I hate to beat the drum but, as I've said in some other replies, I used the official PSU.

If it was one of the original Pi4s you would need to get the FW update that fixed the USB chip power that was the source of many overheating issues -- though that came out relatively soon after release.
