Crucial promises that the MX500 will provide you with a “faster, cooler, and quieter computer” thanks to its adaptable pool of high-speed flash memory to generate blistering speeds. We also love Crucial’s integrated power loss immunity, which preserves all your saved work if the power unexpectedly cuts out, giving you that added reassurance.

i use crucial mx500, based on this info it would seem kernel panic has no affect

^^ kernel panics are not about the hdd or the ssd, it is about code, and the optimized ways to use it.

sigh...

HDDs use the centrifugal motion of the platters to generate electricity after losing power. This electricity is needed to park the heads safely onto the parking ramp or parking zone which is coated so as to prevent stiction or other damage to the heads. If the platters are spinning up at full speed, it'll have more than enough juice to park the heads safely. However, if the power goes off and back on in repeated succession the platters may have just started to spin back up in the last power on and haven't yet reached full speed. So the spinning of the platters may not have enough potential energy to power the parking sequence. In such a case the heads often become fused to the platters.

So. Fear not the "panic shutdown", fear brownouts and storms...
thank you for taking the time to explain this.

    still only 600-700 nits i have to use the contrast enhancer to make bright lights look as bright as they are supposed to but the alternative was the next tier up and buying a demo model that would've been about the same cost, that had 1000 nits but issues with black crush

    Where prices are low

    very dark scenes are more common than very bright scenes so i think i made the right choice

  • The Real Jdbye @ The Real Jdbye:
    there was also a sony with worse local dimming and the glow was really apparent

  • SG854 @ SG854:
    Human vision is non linear anyway. 100 nits is about 50% of the peak output of a 10,000 nit display.

    "very dark scenes are more common than very bright scenes" not in the games i play

  • The Real Jdbye @ The Real Jdbye:
    really have to buy the top end model to get a tv that doesnt have any of those compromises and that would've had more dimming zones too but i am not made o money

  • The Real Jdbye @ The Real Jdbye:
    @Julie_Pilgrim "very bright" is essentially pure white
    Gift
  • The Real Jdbye @ The Real Jdbye:
    pure white doesn't show up all that much it's mainly when looking at a bright sky
    Gift
  • The Real Jdbye @ The Real Jdbye:
    and if the clouds in the sky have slightly less definition to them because i turned on the contrast enhancer who cares

  • The Real Jdbye @ The Real Jdbye:
    that's not important

  • The Real Jdbye @ The Real Jdbye:
    i can't tell the difference

  • The Real Jdbye @ The Real Jdbye:
    but i can certainly tell the difference with black crush if i'm watching a scifi movie and i can't see wtf is going on

  • SG854 @ SG854:
    Human vision is logarithmic, it's not linear. And nits doesn't tell the whole story of perceived brightness. OLED'S look brighter then LCD's even when both are set to the same nit values because of the higher contrast ratio on OLED's

  • SG854 @ SG854:
    OLED's have a 3D look

    Charging port is more likely to fry up or battery fail before the display tbh lol

  • The Real Jdbye @ The Real Jdbye:
    "And nits doesn't tell the whole story of perceived brightness" it's not about perceived brightness it's about all HDR content in TV and movies being mastered for 1000 nits so it doesn't look right with anything lower, it's also about dynamic range

  • The Real Jdbye @ The Real Jdbye:
    "OLED's have a 3D look" no they don't lol

  • SG854 @ SG854:
    As an owner of a OLED and you saying that you never seen an OLED I think I know what I'm talking about lol. I'm not talking about 3D as in 3D glasses. I'm talking about depth and pop in the picture

    I mean to be fair og vitas are still kicking and not many have suffered from pixel bleed and they're going on nearly 10 years

  • SG854 @ SG854:
    OLED's can get away with a lower peak brightness and still provide punchy HDR because of their contrast ratio. Like I said human vision is logarithmic. The higher the peak brightness the diminishing returns in perceived brightness.

    Just get 5 years enjoyment out of it until Nintendy releases something and everyone forgets about switch games lol

  • SG854 @ SG854:
    @The Real Jdbye Oleds hit around 750 nits nowadays. The difference between a 1000 nit and a 750 nit isn't huge. It's only about a 4% increase in perceived brightness. Not huge at all. You'll need at least 2000 nit displays to notice a bigger difference.

  • SG854 @ SG854:
    Read this thread it explains it. 1000 nits is not a huge jump from 750 the LG OLEDs can hit. As I said human vision is non linear.
