I have an old ThinkPad E540 that suddenly shut down on Windows 7 in the fall of 2019. The 1TB HDD reported a fault and the laptop immediately shut down allowing me to later retrieve the data with a live Ubuntu usb. Quite a useful feature from Lenovo, though momentarily scary. And the timing worked out as Win7 was reaching end of life anyway, and I had no intention of switching to Win10. The SanDisk U110 16GB SSD caching drive had been reporting faults for a while, but I ignored it as it wasn't a critical component.
I recently acquired a Kingston A400 480GB SSD to replace the HDD and install and upgrade to Ubuntu 22.04 from my 18.04 usb. I'm considering using the U110 caching drive as swap as I really don't like placing swap-partitions on main SSDs. Which brings me to my question:
Do SSD caching drives have features that make them unsuitable for swap? And should Ubuntu (or Linux?) be able to handle any "bad sectors" in swap?
