  • One thing not mentioned is that modern password hashing algorithms will iterate your password hundred of thousand of times. This makes cracking the hash much more time intensive. For example if 1 hash takes 1ms (most hash algorithms are way quicker), then 1000 iterations of that means it will take 1 second to compute your hash from the input. The server has to spend that time to validate your password when you login, but that’s a small tradeoff to make brute force attempts which will now have to calculate 1000x hashes for each input.

    We updated to the NIST recommendation of 600000 iterations a few years ago when it was released, with regular increases every year. Logins take upwards of 5 seconds but it’s added security in the event the data is leaked.

    Most distros use a generic kernel that contains drivers neeeded for basic operation. These kernels are larger than ones specially made for your hardware. Some specialized drivers like graphics may not be included but will run in a more simplified graphics mode that works for all cards.









  • I have never done RAID over USB, but have done various JBOD setups using SCSI. I think the general idea is that USB having such an easily disconnected connector plus the latency overhead on translating SATA to USB to SATA again means you have a higher chance of corruption. SCSI setups typically have connectors with locking mechanisms to prevent easy disconnection.

    If eSATA is an option it might be better for the performance and it has a latching mechanism to prevent easy disconnection. You can get a 2-port eSATA PCI card for about 50 bucks.

    Oh, and if you have a free PCI port, you could add internal SATA ports to mount the drives internally.





  • With TrueNas you can do it two ways: ISCSI disks that are mounted to the VMs or via NFS. With ISCSI you won’t have access to the data from the TrueNas side as the data will be stored as a volume file. With NFS you get the best of both worlds as you’ll be able to access the files via other TrueNas services like SMB/SFTP. I have my Jellyfin/Plex running via NFS and have few issues, though I’ve not tested it with large 4k/8k videos yet. I mostly run 1080p.
