# PERF 3  How do you select your storage solution?
<a name="peff-03"></a>

 The optimal storage solution for a system varies based on the kind of access method (block, file, or object), patterns of access (random or sequential), required throughput, frequency of access (online, offline, archival), frequency of update (WORM, dynamic), and availability and durability constraints. Well-architected systems use multiple storage solutions and enable different features to improve performance and use resources efficiently.
