Remember that what Jody is talking about the encryption is handled in hardware by the drive controller so performance hit is negligible as they say. Don’t confuse the issue by including consumer level software encryption like FileVault. FileVault is for personal use only. Just making the point for any amateurs out there reading this thread. The people running 4D Server on a Mac Mini and they think “I’ll be more secure and put my data file in FileVault." Yeah, it should work. But I think you would be hard pressed to find anyone that would recommend doing that. And also keep in mind that drive level encryption has no impact on database performance when you are accessing the data cache. No encryption of the data cache and memory. So the negligible decryption performance hit only impacts the first read from disk to load the data cache. And there is a negligible encryption performance hit when writing to disk. But that only happens when the cache is flushed. And the flush happens in a separate thread on a separate core on 4D Server. So that makes it super negligible.
