This whitepaper examines the advantages of Compute Adjacent Storage Architecture (CASA), which uses NVMe SSDs directly attached to processors via PCIe, delivering up to 10x faster data processing at lower costs compared to traditional remote storage architectures. It provides a detailed comparison of cost and performance, analyzing capital and operational expenses over five years and evaluating high-throughput query performance on a 2.5PB dataset using commodity hardware and datacenter setups.
