"Data loss occurred with a Korean and US brand, but it will turn into a whole "thing" if I name them so please forgive me." This does a disservice to those who might be running drives from those vendors with an expectation that they don't lose data post-flush. That said, this narrows one of the data losers down to Hynix. Curious about the other one, considering how many US-based SSD vendors there are.

That said, this narrows one of the data losers down to Hynix. Not really. Samsung builds a plethora of SSDs.

  Per the title, four vendors were tested. Samsung was already mentioned as a non-loser, so it can't be one of the two losers (or else the title would be wrong and the SSDs would be from 3 vendors at most).

    Yeah you got me. I didn't pay careful attention to the wording of the submitted title. I may have been confused because of the wording of the actual tweet: I tested a random selection of four NVMe SSDs from four vendors. The word "random" meant to me that Samsung drives could have been selected twice. But, yes, then there wouldn't be four distinct vendors. Unstated but implied by you is there are only two (major) Korean vendors to choose from. So if Samsung is a Korean winner then Hynix must be the Korean loser. Which is now clear to me. Is it possible there's a third (minor) Korean player? Could I possibly still have a chance? :)

      > Is it possible there's a third (minor) Korean player? Could I possibly still have a chance? :) Well supposedly Zalman (another Korean company) makes SSDs, but I don't think I've ever seen one in the wild. Their specialty is heatsinks and fans, last I checked.

Nobody ahould be expecting that a flush actually flushes because the biggest manufacturer of hard drives tells you it doesn't. Read documents and specifications like this tester didn't do. And don't use random enclosures and pull the plug since the design spec assumes hold up times and sequencing that enclosure may not be compliant with.

  Please stop replying with misinformation all over this thread. The NVMe spec is available for free; you should read it. And you're 100% wrong about the enclosure too. It's driven by an Intel TB bridge JHL6240 and the drives are PCIe NVMe m.2 devices. Power specs are identical to on-board m.2 slots with PCIe support (which is all modern ones). There is no USB involved. See my other reply to you where I explain what Flush actually does (your comments about it are also completely wrong).

    I apologize. Your TB test sounds valid but did you verify with manufacturer that power loss protection or power failure protection works in your TB enclosure? Is that a fair assumption or do you need to ask?
