ZFS offers a number of compression choices when constructing the volume.

[LZ4](https://github.com/lz4/lz4) offers a good balance of compression ratio versus increased CPU usage, and slowed performance. For general usage, we recommend using LZ4.

[zstd](https://github.com/facebook/zstd) is another strong option. This will provide higher compression ratios, but take longer to decompress. We recommend this when storage size is an absolute priority, or for embedded-style deployments (i.e. Raspberry Pi, home IoT setups).

As always, it is best to benchmark your choice to ensure that the performance matches your use case.

:::note

We regularly run tests using *ZFS* with *LZ4* compression. If you encounter issues with other compression algorithms, please let us know.
