I have 4 PiZero based projects. House automation stuff and such. I routinely update the OS, make sure the kernel is up to date, etc. Been using Pi devices since 2012 or so. Thus, I am quite familiar with the devices, the Raspbian OS, micro SD cards, etc. Over the years I have add one or two SSD cards fail, aged or what not. But just in the last month I have seen a marked increase in failures.
Of the 4 PiZero devices, recently updated, i.e. apt-get update and apt-get dist-upgrade commands as usual, as well as checking the firmware/kernel version for each device, 2 failed after reboot. This is odd, since in the last several years, I have had a invalid update happen may one or twice, but never so many same evening? I checked the hardware, using different SSD card image of Raspbian, hardware is fine, both suspect failures booted.
Obviously, the next thing to test if the micro SD cards, and both that failed are now, at hardware level, in read-only mode. Yes, this suggests the SSD cards are failing or have failed. But they were not old per se, less than a year, and other than boots and OS updates about every 90 days, they are for the most part read-only, allowing for the OS write tasking for logs and such.
The micro SD card make and model detailed below. The question is, has anyone else seen a high failure rate of this brand, and/or make or model of micro SD card? I still have several Pi devices running these micro SD cards, and seem fine but maybe ticking bombs, so to speak.
