ZFS vs. UFS — What's the Difference?
By Tayyaba Rehman — Published on January 25, 2024
ZFS (Zettabyte File System) is an advanced file system with features like high storage capacity and data integrity, whereas UFS (Unix File System) is an older file system with simpler architecture and lower storage capacity.

Key Differences
Architecture and Design: ZFS is a modern file system designed for high performance and data integrity, supporting high storage capacities and including features like snapshots and copy-on-write. UFS is a traditional file system with a simpler design and less emphasis on data integrity and performance.
Data Integrity and Protection: ZFS includes built-in data protection features like checksums and self-healing capabilities, providing robust protection against data corruption. UFS lacks these advanced data protection features and relies on additional tools for similar functionalities.
Storage Capacity: ZFS supports very large storage capacities, suitable for modern high-volume storage needs. UFS is designed for smaller-scale storage and may not efficiently handle very large volumes of data.
Scalability and Flexibility: ZFS offers greater scalability and flexibility, allowing for dynamic disk management and storage pooling. UFS is less flexible and scalable compared to ZFS.
Use Cases: ZFS is often used in enterprise-level storage solutions, NAS systems, and high-performance computing environments. UFS is typically used in older systems and simpler storage environments.
