Stores the most frequently read disk data in RAM. Applications that frequently read large amounts of data from the disk will receive much of their data from RAM rather than disk, thus greatly increasing their performance. Also supports writing disk data immediately to RAM and later to the disk (deferred-write, or lazywrite mode), accelerating applications that frequently write large amounts of data to the disk. SuperCache, a block-level cache, complements the higher-level Windows NT file-system cache.

Or a hybrid cache mode which mirrors an entire disk partition or volume. Yields RamDisk-like read performance, without added risk of data loss. Features optional deferred-write mode for accelerated write performance.

Persistence can be realized in three ways: 1) automatic saving the entire virtual disk’s contents during a normal system shutdown and reloading it at system startup or 2) clicking the save image button or 3) utilizing RamDisk's command line interface in a batch file.
