Improve "Laptop mode"Improve "Laptop mode"Posted Oct 7, 2004 18:57 UTC (Thu) by BrucePerens (guest, #2510)Parent article: A general caching filesystem I haven't looked at the CacheFS code yet, but this is what I would like to do with it, or something like it. Put a cache filesystem on a FLASH disk plugged into my laptop. My laptop has a 512M MagicGate card, which looks like a USB disk. Use it to cache all recently read and written blocks from the hard disk, and allow the hard disk to remain spun down most of the time. Anytime the disk has to be spun up, flush any pending write blocks to it. This would be an improvement over "laptop mode" in that it would not require system RAM and could thus be larger, and would not be as volatile as a RAM write cache. Bruce
