To understand Redis, you must understand latency. Reading 1MB sequentially from memory (RAM) takes about 250 microseconds. Reading 1MB from an SSD takes about 1,000 microseconds. Reading from an old spinning disk takes 20,000 microseconds. Redis operates strictly in the RAM space, guaranteeing extreme performance.
