Is it possible to encrypt an SSD without losing performance? As you probably know, when you install an Ubuntu-based distro you are given an option to:
a) Encrypt your full hard-drive, or
b) Encrypt your user folder
If your main drive is an SSD, what do you recommend to do?
I just bite the bullet and go with LUKS. Xts is pretty quick.
Maybe in a few decades we'll have fully homomorphic encryption built into operating systems. The demand is already there with cloud systems.
Only makes sense when the computing provider isn't trustworthy (aka cloud computing). I really hope homomorphic encryption becomes popular and cheap but it's useless for computing on trusted hardware.
You have to be autistic to notice a performance loss with AES
>600 MB/s instead of 700 MB/s
>how will I cope
MB/s
If that's your actual AES throughput you have a shitty CPU.
With the hardware AES stuff you are in the GB/s.
No user those numbers are for SSD read speeds before and after.
Yes? And I was telling the idiot that there won't be a CPU bottleneck unless they are using a piece of hardware without hardware AES units.
Might be a bit different for random IO though, since I think it needs to set up the AES engine more often then, and that could indeed be a limiting factor.
Theft, nigga

Doesn't hardware encryption have backdoors in it?
