The real question is what Western Digital says the speed for the drive is. I would guess that the changes don't touch the stated top speed, as the article seems to indicate that this only slows down write speeds after the cache is filled. If Western Digital specified an average write speed, this might be affected. However, that average could technically not have changed depending on how they determined this average speed (for example, they could have determined this average by downloading and uploading smaller files). I'd say that Western Digital isn't affecting the 0-60 time in ideal conditions, just decreasing the ability of the drive to attain that 0-60 time in less than ideal conditions.

> The real question is what Western Digital says the speed for the drive is. They say "Up to 1,800 MB/s" So if they decided to put in flash similar to a samsung 860 QVO, which drops down to 80 MB/s when the cache is full, that would still satisfy the spec.

  Is this number correct? SSD with cache full can drop to speeds slower than spinning disk drives?

    The low end of QLC is low. https://www.anandtech.com/show/13633/the-samsung-860-qvo-ssd-review https://www.anandtech.com/show/13633/the-samsung-860-qvo-ssd...

      Reading those specs... I don't see any reason to buy it. It is worse than my current 1 TB WD Blacks (spinning disk, not SSD). And much more expensive too! I feel disappointed now... I was hoping SSDs would have been improved by now enough to make them good value for money for someoen that needs crazy amounts of storage.

        The SSD will have a much better latency, and will in practice lead to shorter load times, even with slow QLC. But if you need a lot of storage HDDs still have the better price per GB.

        If you need crazy amounts of storage you are looking at enterprise SSDs which do not have this sort of problem, not consumer crap.

  There's a reason they state the specs using this kind of language. Anyone who experiences performance < 1,800 MB/s is getting what was promised. And anyone who sees performance > 1,800 MB/s is going to be happy. Where it becomes absurd (and amusing, but still not fraud) is when the manufacturer claims "up to XYZ or more!". Any number is going to match that spec. So the statement says nothing.
