Aerospike vs. Redis: The benchmark report is here

Faster and more resilient than Redis. Aerospike is built for real-time scale.

Redis is a well-known in-memory database, but what happens when you need more than just in-memory speed? Aerospike delivers the same low-latency performance while processing more, recovering faster, and costing dramatically less.

This independent benchmark by McKnight Consulting Group compares Aerospike and Redis across 1 TB, 5 TB, and 10 TB 70/30 and 100/0 read/write workloads. The results? Aerospike outperforms Redis in latency, throughput, cost efficiency, and resilience.

What you’ll learn inside

cost-icon

Lower cost, period

Aerospike annual infrastructure costs per transaction were up to 9.5x less than Redis’.

icon speed

Faster, sub-millisecond latency

Aerospike achieved 17% to 48% lower p99 latency than Redis across workloads, with consistent performance from 1 TB to 10 TB.

throughput-icon-2

Higher throughput at every tier

Aerospike handled 11% to 24% more operations per second than Redis, thanks to its Hybrid Memory Architecture and efficient disk access, even in write-heavy scenarios.

accountability-icon

Stronger under pressure

Resilience tests showed Aerospike recovering in as little as three minutes with minimal throughput loss, while Redis took up to 57 minutes and was vulnerable to acknowledged write loss during failover.

Why teams switch

Redis is fast, but keeping it fast at scale means quadrupling instance counts, buying pricier boxes, and hoping failover doesn’t wipe acknowledged writes. Aerospike offers in-memory speed but with persistence,  plus offering predictable performance guarantees. Fewer nodes, lower costs, and higher confidence.
