It's probably just what you might think. You stand up some SSD in front of a magnetic disk, and the SSD can serve as a big, fast, non-volatile buffer for operations against the larger, slower magnetic drive. This is similar to Seagate's hybrid magnetic/SSD 2.5" drives, ZFS's L2ARC, LSI's CacheCade, etc. It's likely to be a read-only cache if I were to guess.
