  • With 4, you are correct, I went from top of my head back what we learned in high school 15 or so years ago. 5 is still better than nothing if you don’t have the resources to get one more drive for 6. Of course, the best is completely mirroring all stuff to a separate geo location.

    It all boils down to willingness of spending money for more durability.

    I’ve edited my comment to scratch R4. But R5 is still great for smaller arrays, and it is possible to, for example, have RAID 5 for movies, and RAID 6 for photos.

    There are also combinations of RAID levels, like aforementioned 10. There is a nice comparison table with apparent drive requirements and fault tolerance on Wikipedia: https://en.m.wikipedia.org/wiki/Standard_RAID_levels


  • You’ll have to find some kind of balance, ad it js a game of chance. You are always limited by number of slots in your server and current largest drive size. Then you are trying to balance price, speed, and durability.

    For exampl, let’s say maximum amount of drives is 10, and maximum manufactured size is 50 TB. You probably don’t need 500 TB of storage that is in no way durable (if a drive dies, all the data on it is lost) and on a single server.

    Death of drives is almost certain, two drives dying at the same time is quite low, so something like RAID 4, 5, 6, or 10 is a great start. Depends on how much storage you want, and then partition it accordingly. If you want 20 TB, you can do 4x 8TB in RAID 5, which yields 3x 8TB (=24) of effective storage.

    Adding new drives is easy, and you are are always wasting just one drive. Then it depends if you want to sacrifice more space for more durability and switch to RAID 6 later on.

    If you want even more storage, you can buy a micro server like ODROID H4+ and use it as network connected storage.





  • From experience: Junie, and AI agent based on Sonnet 4, performs quite well. It can even write tests and fix them if they are failing.

    Not saying the quality is great, but good enough eventually work and to pass as junior code.

    Not sure how good OpenAI agent is, and if they used their coding agent Codex, and if they did then was it as-is or with some tuning? Not sure, they write it was “custom agent based on o3”.

    They write all,the contestants have the same hardware, but did the agent run on the given machine, or in the cloud? Human brain is like 20-40W, so let’s say the upper limit given he has to move his hands - did the AI agent get the same wattage? I don’t think so.
