For me it is most notable in Chrome. Especially on certain webpages such as AVSforum. I can also see it most everywhere in Windows though with the most basic of tasks. Everything is much snappier now. Not that that Samsung was a slog, but the difference is immediately tangible.
It’s also the only reason I would recommend it as an OS drive. For pretty much anything else I think the difference would be imperceptible.
Simple fact, the 900P provides the same latency regardless of queue depth.
