With Redis Enterprise, we recently enabled the ability to extend your RAM-based storage into Flash memory. Don't confuse this with some form of persistence — this is a way to let Redis break out of the bounds of the server RAM and into Flash storage as needed. With the advances in Flash memory (NVMe-based SSD storage), the performance becomes very viable, although not quite as quick as RAM alone. This allows you to have hybrid storage in which data moves between fast RAM and Flash as needed, all managed by Redis Enterprise and without changes to your code.
Let's take a look at the performance characteristics of Redis Enterprise on Flash and how you can test the performance yourself. We suggest installing Redis Enterprise directly as described in our documentation. While we offer instructions on how to use Docker to install Redis Enterprise to test out the product, in this case, that method will not yield the highest performance.
