Samsung Announces Key-Value SSD Prototype

When you say "in hardware", it's not really what you think. These drives generally have low-power general-purpose CPUs in them, like perhaps a little ARM Cortex-M. Any filesystem implemented in the drive will just be regular code running on a different CPU.

I really don't see huge wins here. This will just increase the surface area for bugs, with less ability to fix them, and less ability to recover data when things go wrong.

I definitely do not trust drive manufacturers to write high quality software. It's just not one of their core competencies.

The CPUs may not be as little as you think. Samsung's latest consumer NVMe SSDs - 970 line - can have up to 6 watt TDP at load (and have metal heatspreaders even), and if I remember correctly, the controller is like an 8-core ARM chip that runs at 3 GHz or something. That's more powerful than an Android phone.
