In this Buyer's Guide, DCIG weights, scores and ranks 41 hybrid storage arrays
from 17 companies.
Hybrid storage arrays promise to deliver the dramatic performance benefits of an
all flash memory storage array but at a lower cost since they utilize both flash memory
and hard disk drives. The "secret sauce" varies from vendor to vendor, but in every case it involves sophisticated caching and/or automated storage tiering software.
The key concept that distinguishes hybrid storage arrays from either all flash arrays
or traditional storage arrays is dynamic data placement in a hybrid storage pool that
combines flash memory and traditional hard disk drives.
