It supports advanced features like snapshots, data compression, and built-in RAID. It is widely used in Linux distributions (e.g., Fedora) and enterprise NAS systems for data integrity.</p> <p><strong>zram</strong>: Zram (formerly compcache) is a Linux kernel module that creates a compressed, RAM-based block device, acting as a faster alternative to traditional swap. By compressing data in memory (typically at a 3:1 ratio), it allows systems to store more data in RAM, significantly reducing disk I/O and enhancing responsiveness on low-memory devices.</p>
