It was a lot of fun to write and the feedback I got from readers like yourself made it well worth the effort to put together. Today we are going to extend our basic motion detection approach and: Make our motion detection system a little more robust so that it can run continuously throughout the day and not be as susceptible to lighting condition changes.
Can deliver a very large and fast hard disk cache, though still slower than RAM.
There are usually two types of disk caching: Read Cache - Allows the hard disk to read data ahead in the background, so the application doesn't have to block while waiting for the data to be read, but gets the data delivered from the cache instead.
Write Cache - Allows the hard disk to lazy write data in the background, so the application doesn't have to block while waiting for the data to be written, but enters the cache where it is later written to the hard disk.
How does write caching work? Disk caching greatly improves disk performance, but there is a drawback to Write caching, as anything written to the cache, which haven't been flushed to the disk will be lost when the power is lost. Most applications are aware of this behavior, and the operating system provides the ability to perform a direct write or flushed write.
Write flushing means that the application will wait for the data to be written to disk before continuing, instead of just writing to the cache which completes right away. Several applications was created which was littered with flushed writes, because it performed so well.
These applications performed miserable when used on Windows 95, which didn't have this flaw when performing flushed write, and naturally was much slower than just writing to the cache. One could activate the old buggy behavior by with the option to "Disable Synchronous Buffer Commits", which was hidden away in the troubleshooting section.
Later as server environments have become more and more stable with duplicate power supplies and UPS equipment, then the idea of actually ignoring the flush request has become a wish for those where high disk performance is critical. Write Through - Performs a write to disk without using the cache.
Flush Buffers - Tells the disk to flush everything it has in cache.

Activated by calling FlushFileBuffers. When to enable write caching? The promise of increased performance is always nice, but when the price is the risk of dataloss, then one should be very carefull with changing the behavior of these disk requests. It is also not recommended to enable write caching when running a Database Management System DBMSas these requests are used to create stable commit checkpoints before beginning on a new transaction.
But if having a seperate harddisk for the pagefile or other temporary files, then there can be a performance boost with no cost. How to configure write caching? Windows 7 - The option is called "Turn off Windows write-cache buffer flushing on the device.The CodeWise LLC software development blog.
