Understanding RAID Controller Memory
RAID controller memory, also known as cache memory, temporarily stores incoming and outgoing data. When data is written to a RAID array, it first enters the controller’s memory. This process reduces the time the system spends waiting for slower drives to complete their tasks. In read operations, frequently accessed data can be held in the cache, allowing for near-instant retrieval. The size and speed of the RAID controller memory directly impact overall system performance, making it a key factor in storage optimization.
