&gt; Hello

&gt; I have to upgrade my Kubuntu 10.04 to at least 14.04.
&gt; I have alreay upgraded the hard disk of both laptops to a SSD which =
was
&gt; the most notable performance boost I experienced so far.=20
&gt;=20
&gt; I would like to consider a 14.04 installation with an entirely encry=
pted
&gt; disk. However I fear performance problems and would welcome any comm=
ents
&gt; on that subject.

if you own a ThinkPad already, why don't you use the built-in HD
encryption based on the TPM? You can set a password in the BIOS,
and the encryption is totally transparent to any OS you use. I
use it a lot on machines with dual or multi boot. The *whole
disk* is encrypted, and none of the OSes knows about it. I must
admit that I never tested w/ SSD so far, so I don't know if there
is any impact.
