  • First of all, I’m not defending anyone. You lack reading comprehension. Me saying I interpret this not as a Nazi salute does not imply I like Musk or think he’s not a Nazi.

    Second, I’m not deleting any messages. They got removed by mods for being insulting. So are other messages by other people who insulted me. But you can see that as it says “removed by mods”. Back to reading comprehension…

    Go ahead and save screenshots of my comments and fill up your storage. You realize how this sounds right? You need to relax buddy. This is just a random thread on the internet. Nothing life-changing. Go outside, see the sun.



















  • Nvme and flash in general works very different from HDDs internally and on OS level. It’s a common misunderstanding that SSDs are ready to replace HDDs in all situations. For example, you can actually NOT scale SSD performance linerarly like HDDs would when combining them in a raid. You can also not scale them in size. At some point, the same amount of HDDs will be actually MORE performant than the SSDs in terms of throughput.

    I wrote another related comment somewhere here.

    Servers are an entirely different thing as they use different file systems that optimize on SSDs. Also, they implement layered hardware controllers for the flash chips rather than having a single controller per chip. In servers, SSD might be the future for many use cases. Consumer market is not nearly there yet.


  • There are fundamental problems with how SSDs work. Large-capacity flash might soon become a thing in servers but there won’t be any cost effective SSDs in the consumer market for at least 10 years.

    The problem is how operating systems access the data: they assume a page-organized sequential disk and access the data in that way. SSD controllers essentially need to translate that to how they work internally (which is completely diffetent). This causes latency and extreme fragmenentation on large SSDs over time.

    Instead of buying a 20TB SSD you’re much better buying 4 5TB HDDs. You’ll probably get better write and read speeds if configured in a Raid0 in the long run. Plus, it’s a lot cheaper. Large SSDs in the consumer market are possible, the just don’t make any sense for performance and cost reasons.
