Todays review is of MyDigitalSSDs SuperCache 2 mSATA 128GB SSD, and the FNet HybriDisk caching software. A license key for the HybriDisk software is included with the purchase of the SuperCache 2. How does a caching SSD work? It works in conjunction with a hard drive disk (HDD) to create what the operating system sees as a single, combined storage partition. A caching SSD utilizes specialized software to determine what programs, data, and/or files that the user accesses most frequently. This hot data will be held in a dedicated caching partition on the SSD for much quicker access when called for. Less frequently requested data will still reside on the HDD, until such time as it becomes frequently accessed enough to be moved to the SSD cache. What is stored on the SSD cache is dynamic, and changes over time based on actual usage.
