Yep, valid points.. My current setup suffers from encryption, but it's and auld yoke, from a time way back when they used weird spelling.
The new one is going to be this atom
(without aes extention) on this Jetway
board with 4GB memory in it.
I think I'll just play with it a bit, see what it does. I'll see what the difference is between 2/4 and 4/4 encryption, as you suggested.
Also, I'm planning to encrypt the data disks, not the disk containing the os (which will be an SSD, budget permitting).
But, again, the question is: how secure is 2/4 encryption?
