  • For me, as a user, that’s not my concern. For me, as a user, it’s more important that I can have my convenience

    FTFY

    Also, the only truly bad competition is subsidized competition. As long as it’s not surviving on some kind of grant or funding, instead of its actual market value, then it’s always a good thing as it keeps competitors on their toes.






  • If you have four drives you can do RAID 6 assuming your controller supports it.

    RAID 0 just puts your data on multiple drives, giving you higher read/write speeds but with no built in redundancy.

    RAID 1 is just a copy, you have your data duplicated so that if anything fails there’s an immediate copy. No increase in RW speeds.

    RAID 5/6 use “parity data” which operates somewhat like RNA/DNA when going through mitosis. The four building blocks TCGA only connect with one of the other four in pairs of two, so even if you have half the data (RNA) you know what the other half is by logical extension. The difference is that 5 uses 3 drives at a time whereas 6 uses 4, you can only withstand the failure of one drive in RAID 5 but 6 can handle the loss of two.

    RAID 10 (one-zero, not “ten”) does exactly what the name suggests, it combines the direct copy of RAID 1 with the striping of RAID 0 to give you double RW speeds with redundancy.

    Each one will reduce your overall storage by a certain amount, either because of copying the data completely or taking up space for “parity data.” The only one that doesn’t do this is RAID 0 but you have absolutely no redundancy there and if You’re considering RAID for home use I’m going to assume that’s important to you.



  • SLS is made out of spare shuttle parts and has no reusability, it was also constructed in part by Boeing, known for being the worst of the govvie contractors at making a feasible product. They can’t even make a reliable military aircraft and I worked on theirs so I’ve seen their modern engineering in action. It’s a joke. They’re newest attempt at spacecraft have failed even more miserably than starship.

    SpaceX doesn’t have the newer starship craft functional, but we’ve already used their falcon/dragon system to get off of using Russian spacecraft to visit the ISS and prior to crewed missions were sending them up all the time to restock.

    The SLS is just a bigger and more wasteful version of Apollo, useful to get a group of people to the moon but without enough equipment to set up shop permanently. Not to mention the insane cost because you can’t reuse the spacecraft. US taxpayers have saved so much from not having to fund NASA building their own spacecraft and leaving them to what they do best. Scientific research and mission planning/execution. Everytime a falcon lands successfully the cost per launch goes down, you’ll see the same savings once the kinks get worked out with starship versus SLS’s up front cost of throwing the thing into the ocean everytime.

    SpaceX is to NASA what Lockheed Martin is to the Air Force, a platform manufacturer. The Navy doesn’t build their own jets, they just put out the requirements and let the contractors do what they do best. This is the same concept here.
