Raspberry Pi And The Story Of SD Card Corruption | Hackaday

Posted by jpluimers on 2023/10/02

[Wayback/Archive] Raspberry Pi And The Story Of SD Card Corruption | Hackaday is long and worth reading.

For me the most important bits are how to prevent SD card wear:

  1. use good quality power supplies
  2. put write-heavy operations to SSD
  3. if it suits your use-case, use OverlayFS

The first is always a good idea. It is the primary reason all our electronics live behind a UPS:

In addition, I posted my personal experience (Samsung microSD cards last way longer than SanDisk cards) on Twitter:

[Wayback/Archive] @hackaday I’m have been running a few Raspberry Pi systems with 8-32Gb micro-SD cards as web-dashboard with refreshes every few minutes or so: much write access. When using Sandisk (no matter the type) they last about a year, Samsung (no matter the type) cards last multiple years.

EMP

We had a lightning strike in the evening on 20181111 some 50 meters from our home.

It killed immediately killed this (some pictures further below):

  • Ingoing phase L3 (which is outgoing phase L1) before the electricity meter (the 240V/25A fuse was fully blown); the power distribution company arrived within an hour to fix this
  • The power supply of the microcontroller of our Victron Energy battery
  • A fuse in our solar system
  • The network switch and Apple TV in our living room (which we cannot get to from UPS power due too a building construction issue: the PVC pipes going there are all filled with concrete)
  • The fan/light in one of our bedrooms
  • A few USB power bricks
  • The USB ports of a combined power/USB outlet

Within a few months, 3 more motors of the roller sunshade/shutters died as well as the garage door motor.

Some neighbours had small electronics die. Their bigger electronics survived.

Those were challenging times already (the real struggle began in fall 2019):

So it took a while to get some of the stuff repaired:
