Iíve just been reading something about SD cards dying in the Raspberry Pi (revkís blog). Iím surprised that this is an issue since I would have thought that people get wear-levelling cards. Perhaps they donít do so? I donít know how I would find one, unfortunately, I canít seem to see sufficient detail given when products are listed.

The article linked to earlier refers to an Ďindustrialí so-called small card for sale at RS. I wonder if that is another word for wear-levelling?

My question: How can I move frequently written files to a RAM disk? I would need to find out how to crate one first. Can I then just make a link in order to con the system? (What if it deletes the link?) I imagine that I might want to not relocate/redirect an entire directory, but just one file therein. So if the idea even works what do I do, at boot, move the real file or entire directory to a different device, then make the link to the new location, to be done one time only?

I think I can create a link with ln that will affect files not yet created - is that correct?

One thing you might consider is the Western Digital PiDrive. Have a look at
