We are digital librarians. Among us are represented the various reasons to keep data -- legal requirements, competitive requirements, uncertainty of permanence of cloud services, distaste for transmitting your data externally (e.g. government or corporate espionage), cultural and familial archivists, internet collapse preppers, and people who do it themselves so they're sure it's done right. Everyone has their reasons for curating the data they have decided to keep (either forever or For A Damn Long Time (tm) ). Along the way we have sought out like-minded individuals to exchange strategies, war stories, and cautionary tales of failures.

SD card integrity testing software (alien.top)

Anyone got any idea how I could test if an SD card is starting to fail?

I use many cards in various Raspberry Pi projects some run 24/7

Up until now I have been swapping out the cards as a precaution ever year or so.

This is getting a little annoying so I would like to run some sort of stress test on cards to try and tell if they are failing.

I have about 3 cards that have slowed down a lot so suspect they might be dying (they are not fake i don’t buy cards online I use my local stores that are authorized resellers) they have been in service for a long time.

What software can do this. Guess I need something that’s read and writes constantly and check for inconsistencies

If nothing is available what sort of test should I do and perhaps I could make something in Python.

SD cards are not the most reliable media in general. I would just go with an SSD at this point.

Agreed but I’m doing raspberry pi projects with SSD it’s not cost affective I have currently 9 raspberry Pis that run 24-7 so I would need 9 SSD and 9 USB to SATA adapters. So we are talking about $200 for the cheapest SSD and another $140 for adapters.

9 SD cards about $50
