I know actual, physical RAM drives are rare, but where are they?
Just to be clear, I'm talking about hard drives composed of several RAM slots and a controller acting as an HDD (or more realistically, like an SSD).
I'm aware you have to keep them powered to not lose your data and even if they were SRAM, you could still fit quite a bit on there.
I'm asking: where have all the volatile RAM drives gone? Why are they gone?
@Daniel R Hicks, you answered my question. I would upvote but I have no karma.
