  • 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.







  • Jira would be okay without needless amount of plug-ins, extensions, and dumb workflows one has to follow. Accidentally put it in the wrong state? Enjoy writing to someone who can fix it. Besides, it is slow as fuck and is getting slower with all the tickets (over 80k on our instance) it has to track. Search is shit, and it is shoving AI in my face on every step.

    Plain Jira is not bad. In my second company that I work for, I set up OpenProject and it has been working flawlessly for about 5 years already, it can easily track GitLab commits, branches, and merge requests, and do basic time tracking. It has some nifty features like “budget users” when you want to do budgeting with a “ghost user”.









  • It might be not sending any extra data - which can be verified via packet sniffing like Wireshark - but how do you confirm they are not saving the legit requests you do and collect it silently at the backend? It cannot be proven (beyond reasonable doubt).
