This provides the advantage of having a hard disk drive for maximum storage capacity while delivering an SSD-like overall system performance experience. rnrnISRT works by monitoring which programs and files you access most frequently and stores them on the SSD. As a result, application launch speed and overall system responsiveness are significantly improved, while the large capacity of the hard drive is free to store all your other programs and files. In this configuration, only one drive letter is displayed; no additional drive letter is required for the SSD used as cache.
