I'd really like to go other direction, and have SSDs expose non-uniform storage.

Right now, if my filesystem dies, I have a ton of tools and manuals for recovery. This is the format is well known, and diagnostics tools are easily available.

If my SSD dies, it's just gone. In two cases I had, the drive just was not allowing any file reads at all -- I had zero chance to recover the data. The drive internals are totally opaque.

So no, I would prefer my SSDs to be super dumb -- I do not trust the manufacturers to get recovery tools right.

I'd love to see something like Open Channel SSD's ( http://lightnvm.io/ , https://openchannelssd.readthedocs.io/en/latest/ ) becoming mainstream.

Spec at http://lightnvm.io/docs/OCSSD-2_0-20180129.pdf

> This specification defines a class of SSDs named Open-Channel SSDs. They are different from traditional SSDs in that they expose the internal parallelism of an SSD and allow the host to manage them. Maintaining the parallelism on the host enables benefits such as I/O isolation, predictable latencies, and software-defined non-volatile memory management, that scales to hundreds or thousands of workers per terabyte.
