ScyllaDB vs Apache Cassandra – Performance Benchmark by Samsung

Samsung's Memory Solutions Lab conducted a performance benchmark using the Yahoo! Cloud Serving Benchmark (YCSB) to compare ScyllaDB and Apache Cassandra, revealing that ScyllaDB significantly outperforms Cassandra. The test involved a ScyllaDB cluster with three servers, each utilizing NVMe SSDs, and demonstrated that ScyllaDB can perform 10 to 37 times better than Apache Cassandra when handling a 2TB dataset, even achieving high performance with a lower hit rate where SSDs handled a portion of requests. The study measured latency across different YCSB workloads, showing ScyllaDB's ability to maintain minimal latency while processing high input/output operations per second (IOPS) with a millisecond latency range between 0.6ms to 2.6ms. Samsung's results highlight ScyllaDB's capability to operate efficiently on high-end hardware, suggesting the use of larger machines to optimize performance and reduce total cost of ownership.
