Fast NoSQL from HDDs?

What if you could store huge amounts of data using traditional low-cost HDDs while still maintaining low single-digit millisecond latencies? That’s just what they did at Mail.Ru, the largest email and Internet service provider in Russia.

You’ll see how Mail.Ru uses ScyllaDB to serve up to 240k writes per second with 95 percentile latencies of less than 2ms – using a ScyllaDB cluster running on HDDs.
