btrfs features and specs

• Snapshotting
  Btrfs supports both read-only and read-write snapshots, allowing for efficient data backup and recovery operations without needing to duplicate data.
• Data Integrity
  Btrfs uses checksums for data and metadata, providing robust protection against data corruption by detecting and correcting errors from disk failures.
• Subvolumes
  Using subvolumes, Btrfs provides a flexible way to manage different data sets within a single file system, offering separate quotas and snapshots.
• Compression
  Btrfs supports transparent file system compression, leading to reduced storage footprint and potentially improved read performance by decreasing data transfer sizes.
• RAID Support
  Btrfs has built-in support for numerous RAID levels, such as RAID 0, 1, and 10, which can improve data redundancy and performance without external tools.

Possible disadvantages of btrfs

• Maturity
  While Btrfs has many advanced features, some users experience concerns regarding its maturity and stability, particularly in mission-critical environments.
• Performance Overhead
  Due to its many features such as checksums and snapshots, Btrfs can have higher CPU and memory usage compared to other file systems, potentially affecting performance.
• Complexity
  The extensive feature set and capabilities of Btrfs add to its complexity, which can pose a challenge for users who are unfamiliar with its workings.
• Limited FSCK Support
  The file system check (fsck) utility for Btrfs is not as mature as that for other file systems, potentially complicating recovery processes in case of file system issues.
• Compatibility
  Some operating systems and applications still lack full compatibility or support for Btrfs features, which can cause issues for users who rely on those systems.
