How safe is my data with APFS? Security is one of the key elements of APFS, and it manifests in several ways. First, the file system offers encryption at the file system level, not the disk level as it was previously. (This may seem like a moot point, but it means than encryption is more robust.)

Regarding this, is Apfs encrypted slower?

Using APFS I get write speeds of around 390–405 MB/s. So far, so good. However formatting the drive to APFS (encrypted) results in way slower write speeds of around 250–260 MB/s.

Beside above, how secure is Apfs encryption? So once you've unlocked it, your data is potentially vulnerable. APFS still supports full disk encryption, but it can also encrypt individual files and metadata, with single or multi-key support. That provides additional security for your most sensitive data.
