The reason that hard drives don't use larger caches is because of the risk of losing data if power suddenly shuts down. We all remember the fiasco when Windows OS's powered off the machines before cache dumps; alot of data was being lost and OS's corrupted. The newer ATA133 standard has alot of headroom for huge data caches since the mechanical speeds of the hard drives are so far behind the capabilities of the median. What would it take to make a cache on an IDE hard drive that would be safe from sudden powerloss?
I'm thinking a solid state media solution would be efficient, although transfer rates lag behind hard drive performance.
Trying to use a battery to power the drive until cache has been dumped would be a tricky solution.
Trying to use a battery to power the cache until power is restored is a risky solution.
What ideas do you have?
