Raspberry Pi users have indicated SD cards will eventually fail from wear when booted in the rPi3B+.

I understand that writing to the SD card will eventually cause a failure. SSDs delay this process by engaging "wear-leveling" techniques. It is unclear if agood (Sandisk) USB boot flash drive engages wear-leveling.

Would a USB memory stick suffer the same failure mode as an SD card is is it somehow less prone to a catastrophic failure than a micros SD card, when used to host Raspbian in an rPi3?

In my mind, I am trying to figure out of the order of good=>better=best is:

  • SD-Card => USB-memory-stick => SATA-SSD OR
  • [SD-Card = USB-memory-stick] => SATA-SSD
  • Since different brands/models have different failure rates, you need to compare the expected lifetime of the models you are interested in. Nov 25, 2023 at 1:47
  • Maybe you need to add magnetic disks also. Because all above are flash memory based and have limited number of write cycles Nov 25, 2023 at 18:39
