What is SSD?

[ankitamishra]

Server-based SSDs can function as a cache in the server or as persistent storage, allowing the SSD server to have essentially an extremely fast scratch disk for very frequently accessed data. Putting this high performance storage directly in the server reduces latency because the server doesn’t have to access data on an external storage array. Because of this, server-based SSDs are high performance direct-attached storage. These SSD server drives are typically NAND flash-based.
