Hybrid Storage is defined as a combination of solid-state disk (SSD) and hard disk drives (HDD) in a single storage system.
Two approaches; the first being the more common method of placing SSD drives behind the controller as a capacity tier within the storage system.In the case of Nexsan, their E Series, fits this option should the system be configured with a mix of SSD and spinning disk such as the SAS and Near-line SAS drives.
This second approach is to use SSD to increase the cache memory pool so that I/Os are accelerated before they go through the controller to the back-end disk drives. The larger the cache memory pool, the greater the likelihood of getting a cache hit without having to access the back-end disks—which results in greater application performance.
