  • I used to like the a400, had a few of them in service, but a few years ago I tried another one and it was terrible. Just… Slow… like an HDD. I did some research and apparently they changed something with the nand somewhere along the line. Did a bait and switch. I don’t remember the details but it annoyed me.

    I actually needed to buy a budget SSD just today, and I got a BX500. We’ll see how it goes. I know not to expect much from a drive without DRAM, but at least I know that going in.





  • Thanks, I guess I still don’t understand though.

    I see now that watts and therefore kW are rates. So it’s silly to add another rate to the end by appending “per hour”. But what is the time component of the watt calculation? To me it’s essentially instantaneous, even if that’s wrong. Even if that breaks the math, it’s still essentially true on a macro scale. And if it’s instantaneous, or even just close like microseconds, then it doesn’t hurt to apend another rate to the end, does it?

    So why not use it? Batteries come with capacities rated in Wh and kWh, and it weirdly still makes sense to me because of my usage rate per hour example in my last comment.

    And if we shouldn’t use it, then what should we use?

    Is this problem we’re discussing, one that only occurs if you try to get really accurate with the numbers and times? Because for my uses it’s always seemed to work well enough.

    Not being argumentative, just trying to learn, thanks


  • Wait wait Wait, can you give me more on this kWh thing? I thought I understood this already.

    A single kW is a unit of power, literally 1000 watts.

    A kWh is a unit of energy, as in stored or delivered. Draw 500 watts for 2 hours? That’s a kWh. Or have a battery that can hold 1 kWh, then assuming 100% efficiency you could draw 1000 watts from it for an hour before it was empty.

    All of this is kW times hour, I would say? But in my mind I would interchangeably say per hour as well, they feel the same.

    Obviously I’m wrong, but I’d like to know why lol
