Microsoft Still Trying to Patent Windows Vista's ReadyBoost

The document indicates that Microsoft filed the patent application initially on October 21, 2004 and followed up on February 5, 2009 and May 6, 2010. The most recent continuation was submitted by Microsoft in July of this year in what appears to be an ongoing process to get the invention approved.

Described as "using external memory devices to improve system performance", the document relates to a feature that was heavily marketed during the launch of Windows Vista and is still available, but is largely forgotten by mainstream users today. According to the patent application, the invention covers external memory storage devices that integrate volatile or non-volatile solid-state memory. The idea is to use such a drive "to cache sectors from the hard disk (i.e., disk sectors) and/or slower memory components to improve system performance."

According to the data published, Microsoft found that data read times could be accelerated by more than 60 percent in some circumstances with this technology.

    really!

    real basic idea, and actually I think I came up with it first, so M$ needs to pay me

    Although I admit that I turn off ReadyBoost and Superfetch on every system I use, I still think you guys are talking out your a$$.

    I wasn't aware that anyone else besides Microsoft had implemented a second swap service for faster solid state devices and an algorithm to detect what should be swapped to 'Boost, what should go to normal swap, and what should not be swapped (based on criteria such as the percentage of random io being done on items needing to be swapped).

    Regardless of my feelings that ReadyBoost doesn't work well enough to be worth the hassle, and that it is 100 times better to spend a few more dollars to add RAM.... you should either start listing the operating systems you know of that also do this.... or otherwise kindly stop spouting trash about subjects that make your ignorance shine.

    (And fyi I am aware that most operating systems implement paging priorities, but for the most part they fill the highest priority swap device and move on to the next. They don't subdivide based on workload, so it isn't the same.)
