[Cryptography] LUKS on ATA versus on SSD

[Jon Callas]

My personal opinion is that this is basically BS. There's enough truth in there that it's hard to pry out the silliness.

Every drive today is basically running its own operating system. Yes, an ATA disk is just storing zeroes and ones, but it is doing many of the same things an SSD is doing, like remapping dodgy blocks to good ones. The ATA presents an interface to the driver that is just a bunch of blocks, but underneath, it's complex.

In contrast, an SSD is also incredibly complex underneath and presents to the driver an interface that is just a bunch of logical blocks.

In each case, we have a situation of OMG, complexity is scary, especially when it's so proprietary that we can't talk coherently about it. In all these, there's so much complexity that what we don't know is much more than what we do.

Me, I wouldn't worry about it. Take a laptop that has good user experience for you.
