For some use cases (random access, small rows, hot data set does not fit into RAM) ability to have second level cache on SSD can be desirable. L3 must have support for small rows as well (not only for data blocks). Current L3 index overhead of 64 bytes allows to store efficiently on SSD rows as small as several hundreds bytes.
