A hybrid array is a form of hierarchical storage management that combines hard disk drives (HDDs) with solid-state drives (SSDs) for I/O speed improvements. Hybrid storage arrays aim to mitigate the ever increasing price-performance gap between HDDs and DRAM by adding a non-volatile flash level to the memory hierarchy. Hybrid arrays thus aim to lower the cost per I/O, compared to using only SSDs for storage. Hybrid architectures can be as simple as involving a single SSD cache for desktop or laptop computers, or can be more complex as configurations for data centers and cloud computing.

has abstract
| - Un "Hybrid array", matriu híbrida o matriu d'emmagatzematge híbrid és un tipus de gestió d'emmagatzematge jeràrquic que combina unitats de disc dur (HDD) amb unitats d'estat sòlid (SSD) per tal de millorar la velocitat d'E/S. Un cas semblant però no tant ràpid, és el ReadyBoost de Microsoft que permet als ordinadors personals emprar unitats flash USB com a cache de disc. Les matrius d'emmagatzematge híbrid tenen com a objectiu mitigar la diferència de preu-rendiment cada cop més creixent entre els discs durs i la DRAM afegint un nivell de disk cache búfer a la jerarquia de memòria . Així, les matrius híbrides pretenen reduir el cost per cada E/S, en comparació amb l'ús només de SSD per a l'emmagatzematge. Les arquitectures híbrides poden ser tan senzilles com incloure un únic cache de disc SSD per a ordinadors d'escriptori o portàtils, o poden ser més complexes com les configuracions per a centres de dades i cloud computing, que poden implementar un webcache.
