Comparison of NVMe over Fabrics and iSCSI storage protocols in terms of performance, scalability, and cost
Updated July 1, 2026
NVMe over Fabrics
Best when high-performance, low-latency storage is required, such as in cloud deployments or data centers
iSCSI
Best when cost and compatibility are primary concerns, such as in small to medium-sized businesses or legacy systems
NVMe over Fabrics is the clear winner in terms of performance and scalability, but iSCSI remains a viable option for users who prioritize cost and compatibility over raw speed and reliability.
