Which file system offers RAID-like redundancy and ongoing integrity checks?

The choice that provides RAID-like redundancy and ongoing integrity checks is the Resilient File System (ReFS). ReFS is designed to improve data availability and protect against data corruption, employing features that are beneficial for high-capacity and high-integrity workloads. One of its notable characteristics is its ability to perform integrity checks on data stored within the file system, which is crucial for ensuring that data remains unchanged and accurate over time.

ReFS utilizes a concept of checksums to verify the integrity of data and can automatically repair any corruption using mirrored copies of data. This is especially important in environments that need to maintain high data reliability, such as running virtual machines or in data storage solutions requiring continuous uptime and data correctness.

While NTFS does provide some level of file system integrity and journaling, it does not offer the same level of built-in redundancy and automatic repairs that ReFS provides. Therefore, ReFS stands out as the file system that best fits the requirements for redundancy and ongoing integrity checks.
