Hardware, Embedded Systems "In the past five years, flash memory has progressed from a promising accelerator, whose place in the data center was still uncertain, to an established enterprise component for storing performance-critical data. It's rise to prominence followed its proliferation in the consumer world and the volume economics that followed. With SSDs, flash arrived in a form optimized for compatibility - just replace a hard drive with an SSD for radically better performance. But the properties of the NAND flash memory used by SSDs differ significantly from those of the magnetic media in the hard drives they often displace. While SSDs have become more pervasive in a variety of uses, the industry has only just started to design storage systems that embrace the nuances of flash memory. As it escapes the confines of compatibility, significant improvements in performance, reliability, and cost are possible."

True, but from what I understand, that's more like swap space and it can't achieve the same compression ratios as data-aware formats like PNG. (Remember, PNG performs various transforms before DEFLATEing)

Agreed. They're talking about using XZ compression, so it's just bulk compression rather then specific compression, like in the case of PNG.

I suppose it could work as long as there's a strong effort to shame and shun any applications which put their caches somewhere that can't be expired independent of their cooperation or knowledge.

It's the OS that manages that, so I don't think applications have any say in the matter, which is how it should be.

I was under the impression "the most common size" for a PDF was "Fit Width"

And full page in window.

Also, I'm Canadian. I've got 5Mbit/800Kbit Internet and every member of my family (my writer/artist mother, my gamer brothers, my non-gaming, programming self, etc.) can never have enough disk space so wasting space on easily-regenerated caches for rarely-used files is not acceptable from a storage OR a transfer perspective.

Right, that's why the render cache shouldn't be stored with the original file, which is what I was pointing out.

There are lots of techniques and algorithms for cache management. The OS should keep the render cache at a reasonable size. We have enough CPU/GPU power now that re-rendering, or rendering everything on the fly, isn't the performance hit it used to be.
