100xCD Cache speeds up your CD-ROM drive by caching frequently accessed data to your local hard drive. It work under Windows-XP/2000. How it works? Every time an application attempts to read data from a CD-ROM drive, 100xCD intercepts and analyzes this activity. If the application attempts to read the same data for a number of times (many multimedia application tend to do so), 100xCD then puts this frequently accessed data chunk to it?s cache on a local hard drive. Next time the application will read this data chunk directly from the hard drive. Unlike system-provided RAM-based CD-ROM cache, 100xCD's cache can be very big (up to 1000GB) and hold data for unlimited amount of time. Modern hard drives and RAID-devices are much faster than any CD-ROM drive available on the market (in both access time and transfer rate), so the overall performance increases when using 100xCD.
