	abstract = {<p>Modern storage systems are becoming more complex, combining different storage technologies with different behaviors. \&nbsp;Performance alone is not enough\&nbsp; to charac- terize storage systems: energy efficiency, durability, and more are becoming equally\&nbsp; important. We posit that one must evaluate storage systems from a monetary cost per- spective as\&nbsp; well as performance. \&nbsp;We believe that cost should consider the workloads used over the storage sys-\&nbsp; tems{\textquoteright} expected lifetime. \&nbsp;We designed and developed a versatile hybrid storage system under Linux\&nbsp; that com- bines HDD and SSD. The SSD can be used as cache or as primary storage for hot data. Our\&nbsp; system includes tun- able parameters to enable trading off performance, en- ergy use, and\&nbsp; durability. We built a cost model and eval- uated our system under a variety of workloads and pa-\&nbsp; rameters, to illustrate the importance of cost evaluations of storage systems.</p>
