  1. Questions regarding 8tb drives...

    I thought so. Well it is next on my list, to replace the REDs with Ironwolfs. but thank you for your input.
  2. Questions regarding 8tb drives...

    According to this site, your disk is running 5900RPM. that is a tad faster than 5400RPM. But my logic tells me it should not differ more than 20-30 min. 1 hour tops. It could be my system is discontinued components from an old datacenter, (except the disks). I mean my SATA controllers are only SATAII, yet mb/s wise I should never hit the speed limit of that controller. But there may be instruction in SATAIII that could give a performance boost. But again I can get the math to fit with that big of a time difference. I guess I will see on Monday when the parity will run again if my cache drive will make a difference (just installed it today). I know it will not speed up the process, but I may spare some writes, and that should help on the time, but not much. I save all my photos (I am a part time photograper) on this system, with backup to a local qnap, and also a backup to a long distance qnap. I use the parity to prevent bitrot, yes I know it is not meant for that. But then let us call it "off label use".
  3. Questions regarding 8tb drives...

    My setup take: Last check completed on Monday, 2018-02-19, 22:08 (two days ago), finding 0 errors. Duration: 23 hours, 8 minutes, 51 seconds. Average speed: 96.0 MB/sec with a mix of Ironwolf from seagate an RED from western digital. How I wish it only took 18H. But In future I plan to replace the REDs with IronWolf. Then it should speed things up. I may even hit that 18H mark. /Alphahelix

  5. Questions regarding 8tb drives...

    But parity / rebuild will be roughly twice as fast with the 4TB vs 8TB (assuming same mb/sec performance) and with 8TB @ 5400rpm it takes roughly 24H to complete a parity check. Not imperative, yet still a factor I think is worth mentioning.
  6. I know this is a rather old thread. Yet for others having same needs, I would like to give a possible solution for this. If you pass through an USB controller. Not sure if it is possible with one port, as I believe any and every objects in an IOMMU group needs to be passed through, all at once. But if you manage to pass through an USB port you can attach a USB optical drive or just drive to a VM. I cant see why it wouldn't work. As it should not be any different than my setup, where I pass through my keyboard and mouse to my Windows.
  7. FTP Server - WebGUI options

    I have disabled FTP on my unRaid. When not using it, better disable it. But I also know some cases needs the FTP. So instead of removing it altogether, why not disable it as default?
  8. WiFi rather than Ethernet only for unRAID

    yet the router/bridge/AP solution requires a transformer that will suck unnecessary power to run the unit. Whereas an internal wifi-card will only use the power required for the card(s). I know it is not much, but for a 24/7-365 setup it will accumulate to noticeable amounts. That said, my setup (once all my parts arrives [read once I have the coin to buy them]) will be a managed poe switch to switch two WAN to one socket (I have two public IP) and a unify AP, to reduce power consumption.
  9. file browser in webui

    +1 even if MC via ssh is ok, its not great. I have tried Krusader via docker, but it is no longer maintained.
  10. Do you use spin up groups?

    I dont use them. But if I could have a saying then leave tje feature for people to fine tune their system.
  11. Maybe a slight re-write: "one box that serves all!" Another one thought is that I have friends that buy themselves poor in Synology and Qnap boxes. With that thought this could be an idea: "You bring the hardware, unRAID delivers the rest!" If they are poor I apologize... But its rather late here in little Denmark.
  12. Adding an Encryption Layer

    +1 for encryption on share level. also... +1 for cache/array encryption.
  13. Crackling sound in VM (via HDMI)

    I gave up on HDMI sound and bought a cheap USB sound card and passed some USB ports through to solve this. and it works... sort of. it sometimes drops, but I do think it is due to my 15-20m long usb cables.
  14. Balance after Mover Runs

    When reading this thread, I cant help to think of a more refined solution where the mover as it is today runs as it always does. but at a user defined interval (day/week/month/quarter/year) runs the balanced-mover. that perform the above mentioned task.
