  • RaidZ1 is not the same as a mirror. I’m not sure if you are allowed to have Z1 with only 2 disks, but if you are you still shouldn’t because while it scales down that far it still does parity calculations and writes that to the second disk instead of just writing a copy of the data (the parity calculations probably result in the same data, but I doubt this is optimized)


  • ZFS snapshots are easy to settup. If you don’t notice that you deleted all the snapshots for a month you never will.

    you still should have offsite backups for a fire, but the notion that raid isn’t backup is not really correct since for most people the situations that raid with snapshots isn’t enough protection will never occure and to the risk is acceptable. Plus raid is a lot easier to get right. For that matter if you have a backup but don’t have the password after the fire you don’t have a backup.

    though if you rely on raid alone I’d want 3 disk redundancy.




  • I only have leagally owned movies. I’m technically violating some law but since I can show the judge the originals and they are not available outside myhome they won’t dare go after me - a jury won’t convict and even if one would I’m a perfect ‘normal man’ who proved the law is unjust. I won’t be as well known as Rosa Parks in history but I’d be a perfect story to rally around to get the las changed and they won’t risk that



  • Yes. However as others have already said odds are you don’t have the right devices. Still if you really work at it everything exists. Start by selecting one of the few TVs that support it, then get a good HDMI cable, make sure you have a video card that supports it, with drivers for the OS (you might have to write them yourself), then just setup networking. This would be an interesting hack, I’d love to see someone get it working and show their setup, but it is otherwise useless and will be a lot of work.






  • FreeBSD - it won’t be easy, but I’ve been a BSD guy at heart for decades… You will learn a lot and eventually be able to create better systems, but it will be years before you should risk putting anything important on a system - as a noob you have a lot to learn the hard way. Once you think you know FreeBSD you should try the other BSDs, and things like gentoo linux: you will really learn how this works.

    You can follow the advice of the others and get a system going sooner. It isn’t a wrong choice, but you won’t learn as much and if something doesn’t work the way you want you are stuck since you can’t dare change anything. As such I have to advice against it despite all the time/effort my advice will cost you.






  • Or is it better to save a few bucks now and save it for next year when something new comes out that is faster anyway. Maybe there is a new codec that matters in 3 years but nothing today supports: so either way you are forced to replace your server.

    There is no right answer, you are taking your chances when planning for the future. There are many computers more than 10 years old still working just fine in the world, and it is possible that whatever you buy today will be as well. We get enough press releases that we can predict what will happen next year close enough, but in 5 years we have much less information. There is no way to know if saving money is a good choice today or not. I can come up with scenarios either way.

    Look at power use. Often last generation hardware uses more power for the things you do today and so the few dollars you save today are made up with in the power bill over the next couple years. (though if you use that new hardware to do something the old couldn’t do the new will use more power!)

    If there is only a few dollars difference in price go for the best. However when there are hundreds or even thousands of dollars it becomes a harder decision.




  • Parts fail all the time. The problem with hardware raid is you need a compatible controller or none of the data can be read even though it is still on the physical disks. Computer hardware is often only made for a few months before there is a new model and so you are risking that the manufacture really made the new model work with what you have. That is assuming the manufacture doesn’t go out of business which could happen without warning. \

    Also, if hardware breaks that is often a good excuse to replace it - odds are better hardware is available for the same price and sometimes a lot less $ - with hardware raid you are stuck paying whatever price they charge.
