    On the topic of if the Samsung driver can do "better", there's no question (this was my primary area of work, back when, driver stability and compatibility).

    Think about how some drives have an optimized cache, and without a stack driver, the storage stack will just write blindly (it still does, with the IHV driver, but...), and likely the cache will be subverted, or under-utilized, particularly if you chose to disable "write caching".
    In other (more generic) cases, perhaps the driver manufacturer knows that certain block writes are poorly handled, or handled better in a slightly different size(s). In this case, the IHV stack driver can assist at coalescing these into more optimized formats (and in some cases, it can report some of this capability back up-stream, to the primary or volume driver).

    Sure, some IHVs (and a few OEMs) tend to make more of a mess than help in the driver department (cough, cough, Intel...), but for the most part, they do a decent job of adding value. In some cases, they add significant performance value.

    Some just add their splash logo, and a couple of version changes, and then post, it's pretty common to see this type of thing with ASUS MB updates, IME. That's okay, they've just increased your one-stop shop value of the ASUS support site. Hopefully they push them through WHQL, and they come down (to more people, typically) through Windows Update, this seems to depend a lot on the age of the device/system.

    My benchmarks with new Samsung NVMe driver vers 2.3.1709

    Thank you Neobeum, ItzyCharles and others for posting that Samsung released NVMe driver vers 2.3. I am still getting similar seq read/write speeds as the vers 2.2 driver:

    which is fine. However, Magician did want to re-run my over-provisioning with the new driver. I set aside 10% for over-provisioning, at least until the day when I'll need that space:

    So I'm running the 2.3 rev now, and it's crazy-fast, I was pretty much blown away (obviously the Magician numbers, but still a HUGE improvement).

    This is all FCU (same OS build), here's my numbers (see pic at bottom). Also all NVME mode, hanging off the SCSI\NVME node, see my previous post.
    Before this I was getting ~2800/~1800, on a good day, with nothing running.

    This is with quite a few other processes running, and it STILL blew by my old FCU/Samsung 2.2 Driver numbers.
