Basho LevelDB supports tiered storage
Tiered storage is turning out to be a pretty practical trick to take advantage of SSDs:
The justification for two types/speeds of storage arrays is simple. leveldb is extremely write intensive in its lower levels. The write intensity drops off as the level number increases. Similarly, current and frequently updated data tends to be in lower levels while archival data tends to be in higher levels. These leveldb characteristics create a desire to have faster, more expensive storage arrays for the high intensity lower levels. This branch allows the high intensity lower levels to be on expensive storage arrays while slower, less expensive storage arrays to hold the higher level data to reduce costs.
