  1. That's not rot, that's an error. URE's would still be logged (in theory) as an error by the drive and can be immediately recognized if monitored by the OS. The theory is that it will pretty much guarantee the death of a normal RAID implementation since drives are well above 12~ TBs now, and read failures during a, for example, RAID 5 array will drop a disk during rebuild and thus the array will be lost. It's only theory tho, as the MTBURE is not set in stone. It's a guess as to the chance, and even then the drive is likely to recover from the error anyway. IMHO, bit rot and URE are WAAAAAAY less important to worry about than just keeping backups of your important data, and verifying your backups
  2. Yes. But unlikely (random cosmic ray blasts a bit on the drive for instance), the drive would still likely report a read error. Data "decaying" in any reasonable amount of time, really unlikely.
  3. It'll look like this, then you can match the serial# to the disk #:
  4. Anything behind your VPN does not require any other paid services to access, you simply connect via a client to your VPN to access anything behind it. Anything you want to access OUTSIDE of your network can be done thru a paid VPN, but the two are mutually exclusive.
  5. What are you trying to use the VPN providers for? If your services are behind your VPN, you just need to access the VPN with your client.
  6. Keep splitters to a minimum if at all possible, and no more than 4 drives per molex connector or you will start to exceed it's current handling capability and the drives will start behaving badly (it's also a fire hazard)
  7. At my age, I don't want to work through anything, i want to crack a beer and press play
  8. Generally, reallocated sectors are a pre-fail indicator. Without any other details, it's impossible to comment on your specific situation, but for me any bad sectors is a drive failure and I replace. All drives are needed to rebuild any other failed drive, so using sketchy drives in the array isn't worth it.
  9. With all of the network gear, and POE cameras, the whole rack runs about $30/month to run 24/7
  10. The problem with sketchy disks in a parity/RAID environment is you still need all of them to work when they're needed most.
  11. For a NAS/media server, I'd say not even a little bit. I'm not an Intel fanboy or anything, but it just works. If you like tinkering or need a crap-ton of I/O, then AMD.
  12. For Plex, Intel as the new iGPUs are all you'll need for transcoding.
  13. Definitely make sure you have your power delivery well thought out, avoid splitters at all costs or you'll start having issues. Sonarr along with Prowlarr. You can set up default quality profiles, and manually change individual shows *cough*linux distros*cough* if needed.
  14. Indeed, and far less than that would be from "silent" corruption. Drives have ECC already for just such things and would start spewing SMART errors if it could not be corrected on the fly. If they lost a quarter of their data, it ain't from bit-rot lol
  15. Unraid has a GUI option under Tools->Diagnostics
  16. It's not the rails, or the power supply for that matter - it's the molex connector itself. Going above 4 drives per connector and you start to reach its current limit and it's no longer able to maintain stable voltage under load (and may burn).
  17. Read speed isn't affected by using SMR drives. You have another bottleneck you need to find and resolve File size has no real bearing, either. 4k tops out at like 80 or so Mbps, note the little 'b'. Much lower than even SMR drives are able to read.
  18. Yes, 1 connector for each backplane, spread across at least 2 lines back to the PSU (preferably 3). You can use your unused SATA power lines by adding your own molex connectors directly to the line using punch down style connectors like mentioned elsewhere in this thread: https://www.moddiy.com/products/DIY-IDE-Molex-Power-EZ-Crimp-Connector-%2d-Black.html That's exactly what I did and it's been solid since.
  19. Each molex connector has a limit, and each connector at the PSU has a limit. Voltage is a finicky b*, and any sags and the drive can reset. Sata to molex isn't the most reliable, but should work in a pinch. Long term, my suggestion is to add proper connectors to additional lines. 3 planes (3 individual molex connectors) x 2 lines to the psu. Better yet, 2 planes x 3 lines would be optimal
  20. Just to add, think max 4 drives per connector, and not all on the same line. The PSU is plenty, but you have to spread the load
