A storage system is provided that includes storage controller logic that performs rapid data snapshots. The storage controller logic may provide block-level access to a storage volume. The storage controller logic may store all data blocks of the storage volume in a first solid state memory cache. The storage controller logic may form a snapshot of the storage volume in a second solid state memory cache. The first and second solid state memory caches are addressable with a processor. The storage system may complete the snapshot extremely quickly because the processor may copy from one memory location to another between the first and second solid state memory caches.
