Interesting that the one has such large capacitors in it. I imagine that is as last-ditch effort to keep the board powered long enough to finish flushing all of its caches in the event of a power failure.
That's exactly the point of power loss protection (aka PLP.) As a side effect of not needing to wait for a flush after a write synchronous write workloads are dramatically faster on enterprise drives with PLP.
Edit: To add a bit of detail - you don't need to wait for a flush after a synchronous write with PLP because the drive firmware can lie and immediately return from a flush call because there's enough backup power to complete that flush if the power were cut.
They'll also start paring features out of the device as soon as it's convenient for them, like they did with the OnHub as soon as Google Home devices launched. I'm still salty about the OnHub, they flat out neutered a multifunction device down to a big WiFi AP because they just didn't want people using any of the smart home or speaker functionality once they had other products to sell.
I mean, it's pretty straightforward to run sting buy operations and then go after the platform selling illegal products. I'm surprised there isn't an ATF taskforce devoted to combing the usual internet marketplaces and then filing federal charges.
I don't use Samsung unless I plan to unlock and root the device. I have 70+ apps disabled on my Samsung tablet and it's finally usable. Hopefully someone else comes along with a high spec OLED tablet sometime soon so I can stop buying Galaxy Tab S devices.
