To store them more efficiently, you can enable erasure coding. Benefit -* Efficient memory usage and faster startup time.

Compared to 5x data size, it saves 3.6x disk space. +* SeaweedFS uses continuous 1GB block layout with 1MB block sizes for edge cases, optimized for both small file reads and storage efficiency. +* Efficient memory usage and faster startup time.
