+## Compression choices
+
+ZFS offers a number of compression choices when constructing the volume.
+
+*lz4* offers a good balance of compression ratio versus increased CPU usage, and slowed performance. For general usage, we would recommend using *lz4*.
+
+*zstd* is another strong option. This will provide higher compression ratios, but take longer to decompress. We would 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 run CI tests using *ZFS* with *lz4* compression. If you encounter issues with other compression algorithms, please let us know.
