That entirely depends on what your threat model is. You may not get any value out of that feature, but others may want it. One reason may be ease of storage drive disposal upon drive failure; i.e., if your drive is unencrypted and has your personal photos on it and it fails, the data is still recoverable with no easy way for you to destroy the data. If it was encrypted at rest, you wouldn’t have to worry about it because you would only have to rotate the encryption key.







Why should I use a raidz array? I use other scalable storage solutions. Encryption at rest is a standard core tenant to cybersecurity. If one of the raidz drives is removed from the array, and you’re not encrypting your datasets, someone could recover data from the drive.
