Yeah, it&#x27;s true - same for anyone.  The main benefit of encrypting the drives (indeed, the only reason I was willing to do the tradeoff for something which is mostly theatre) is that we can RMA failed drives and discard old drives with no risk to customer data.<p>That alone is worth paying the slight overhead on modern CPUs for full disk encryption of all user-data partitions (the OS isn&#x27;t encrypted - it&#x27;s Debian with some open source packages on it, and we throw it away anytime - <a href="http:&#x2F;&#x2F;blog.fastmail.com&#x2F;2014&#x2F;12&#x2F;07&#x2F;automated-installation&#x2F;" rel="nofollow">http:&#x2F;&#x2F;blog.fastmail.com&#x2F;2014&#x2F;12&#x2F;07&#x2F;automated-installation&#x2F;</a>)
