Beyond the Price Gap: Redefining Enterprise TCO with QLC Flash for Massively Distributed Object Storage
As QLC NAND densities reach 61TB and beyond, the storage industry is rapidly approaching a strategic crossover point with high-capacity HDDs. However, raw acquisition cost remains a significant hurdle for many enterprise users. This session presents a comprehensive joint study by Scality and the Samsung Memory Research Center (SMRC) introducing the "Performance TCO" (PTCO) model. We move beyond simplistic $/GB metrics by benchmarking real-world datasets across hundreds of diverse HDD platforms globally and comparing them directly against lab results obtained on SMRC QLC platforms. By examining 16KB cell alignment, Write Amplification Factor (WAF) in sequential SDS workloads, and high-throughput use cases like Veeam Backup & Replication targets, we illustrate how QLC is positioning itself as a vital economic and performance-driven alternative for modern high-density object storage environments.
