BSD and Darwin derivatives "FreeNAS is an open source operating system based on FreeBSD and, as its name implies, designed for networked storage. The project recently celebrated the release of FreeNAS 8, which racked up some 43,000 downloads in the first 48 hours after its release. I caught up with Josh Paetzel, director of IT at iXsystems and project manager for FreeNAS 8, to talk about the current state of the OS, what lies ahead for it, and the relationship to FreeNAS 0.7."

Encrypted volumes protect your data if someone gets physical access to your hardware so I understand why someone would want this on laptops and home computers and things that could be stolen.

What is the benefit of encryption on production NAS systems? Would it just slow things down?


There is some performance penalty for encryption, unless you have an Intel CPU that has AES-NI. Most of the laptops have it now, and a good number of the desktop CPUs have it. It seems to remove most of the performance penalty for encryption.

If you run Truecrypt and have an AES-NI processor (only Intel has them right now) then you can also make use of the acceleration.
