It would suck donkey balls of course.

Nobody wants their CPU donating a couple cores, to make
up for the ARM cores the SSD has. One of my SSDs has a
three-core ARM, two cores are for error correction on read!
And that is not particularly unusual.

Imagine if your SSD was slowed down by a slack-jawed "raw flash"
storage device. That would be awful.

The partitioning is the way that it is, for a reason.

The faster that storage devices get, the more sensitive they
become to details. This is why I would keep you well away
from my PCIe Rev5 NVMe at 14000/12000 MB/sec. That still
needs an error corrector, and somehow keep up with the
need to correct every sector being read out. It's one
of the reasons those get so hot (and they put toy heatsinks
on top).

That's also how you can have devices like this. You would not
get these sorts of rates, without IOPs in the picture to help.
