Well, took about a day in the end... Wonder how long the SD card will hold up with the write load from swapping...
@paradroyd Yeah, I've had good luck with some, but it isn't really predictable. One of my cards has just stopped performing writes (without throwing errors), for example, and I don't know of any health indicators - though, as you say, watching out for increasing latency might be an indirect one.
That's where the process I'm using to update the images works for me me.. I'm using Terabyte Unlimited imaging tools that verify the images and I know exactly how long an image should take to write. Should be just over 4.5 minutes. If it takes much over 5, I retire the SD card.
I've seen less and less getting slow over time as I've shaken the "weak" ones out of the process.
