How fast is flash?

With Redis Enterprise, users can now extend their RAM-based storage into flash memory, enabling hybrid storage that moves data between fast RAM and flash as needed. This allows for high-performance storage without requiring changes to code. To test the performance of Redis Enterprise on flash, users should use i3.2xlarge AWS instances with NVMe SSD drives, and a memtier_benchmark setup that simulates realistic access patterns. The benchmark shows an average throughput of over 100,000 ops/sec at sub-millisecond latency, making it suitable for many real-world database use cases. Using flash as a RAM extension provides significant savings compared to running a RAM-only version with three times the infrastructure cost.
