To store them more efficiently, you can enable erasure coding. -Benefit +## Benefit * SeaweedFS implemented RS(10,4), which allows loss of 4 shards of data with 1.4x data size. 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. The volume server does not load index data into memory. + +## How to enable it? \ No newline at end of file
