"World's first" Open-Source storage engine for SSDs? I believe Aerospike has advertised itself as that for years, and certainly most MongoDB instances are backed by SSD these days. Heck, conceptually etcd is a key-value storage engine built for SSDs.

Orchestrating data placement? Isn't that what all storage engines do?
What am I missing here? Is this a block level rather than file-system level driver?
