 Warm data are accessed less frequently. To store them more efficiently, you can enable erasure coding.

+## 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.
