My guess: PlexTurbo is really deduplication:

“PlexTurbo will dynamically create and compare data patterns then merge
the same command data into one buffer to accelerate write response speed”

If you look at how something like ZFS does dedupe, you pay for it with a bit more CPU (to create the hashes used to compare for duplicates) and RAM (to hold a copy of the hash table in RAM)… but CPU is effectively free, and trading RAM for performance is something most users are willing to do. You’re protected from power-loss because that hash table is always in the SSD too: PlexTurbo is just a way to also get it out as a copy in memory.

Dedupe can show big wins for things like virtualization and backups… but on a desktop I don’t think it would help much: so I may be totally wrong in my guess.

Somebody needs to develop an interconnect for motherboards to utilize a 12v battery for exactly what shinra mentioned. They could use a sealed lead-acid battery just like in alarms only a smaller one, which would interconnect with a motherboard. It would then be used as either the primary power source or used as a backup in the event of power loss. Either way best configured how laptops are. In laptops and tablets they already have the battery permanently installed, so no need to worry about that. Ram prices and quantity in laptops and desktops just needs to drop and increase accordingly.

I would like to know how PlexTurbo would protect against power loss. I don’t see how it is possible if they are caching it over on the RAM and the RAM doesn’t have any power loss protection.
