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."

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.

My original point is that NVRAM wouldn't change anything here. If Evince or Okular supported a non-volatile render cache, I'd turn it off to save space since I have many many PDFs, use each individual one infrequently, and always have less space than optimal. (I collect things like YouTube videos)

As far as PDFs go, I usually just read a research paper or electronic component's data sheet, write a library, circuit diagram, or take notes, and then keep it around just in case.
