On top of that, when set up to support your boot tasks only, there's no write activity to wear it out. > And what about booting from an USB stick? Just as good, technically, IMHO.

I like Ed W's suggestions, as well, with the caveat that their usefulness would make them more likely to be "borrowed". Even by yourself, in a pinch. Phil
