I hope your CPU has AES-NI.
A powerful i7 does AES at 50MiB/s (don't remember exactly, but below 100MiB/s)
without AES-NI and about 900MiB/s with AES-NI.
SSDs speed is usually around 250MiB/s, so AES-NI is required to maintain speed.
Additional hint: I would avoid xts modes, as the speed is halved (450MiB/s)
for not really convincing security reasons.
I'm running AES with NI on a SSD and the CPUs are almost undisturbed by disk
activities.
Cipher name: aes
Cipher mode: cbc-essiv:sha256
Hash spec: sha256
Thanks Roberto.
Yes, I have AES-NI in my i7 cpu.
