# Cons of Cassandra

**Slow reading.** As Cassandra was initially designed for fast writing, its weakness lies in its incapacity for fast reading. One of the reasons for it is that there are no bottlenecks for information sent, so it needs more time to process.

**Need for additional resources.** As Cassandra processes multiple layers of data simultaneously, it demands enough power to do it. This means additional investment in both software and hardware. If this is the first time a company faces such a necessity and is not sure about the resources, then maybe it should consider other database systems.
