ZFS hybrid storage pools intelligently combine DRAM, flash, and hard disk drives to achieve the right balance of cost and performance for any given working set, while reducing the need for administrators to constantly monitor storage for I/O bottlenecks. By reducing both read and write latency with the use of flash in a ZFS hybrid storage pool, we end up with a system that performs far better than legacy storage systems, while having a much lower total cost of ownership (TCO).
