With the risk of going way off topic

At my age, I don't want to work through anything, i want to crack a beer and press play

Ditch the banner and you may pry 6.8.3 from me yet

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.

With all of the network gear, and POE cameras, the whole rack runs about $30/month to run 24/7

The problem with sketchy disks in a parity/RAID environment is you still need all of them to work when they're needed most.

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.

For Plex, Intel as the new iGPUs are all you'll need for transcoding.

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.

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

Same here with 3 different providers

Unraid has a GUI option under Tools->Diagnostics

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).

+1 And turn on notifications

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.

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.

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

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

This is what I did to add extra connectors to one of the unused sata lines. Easy enough to tone out with a basic multimeter (use a splitter to check all diy connectors tone out the same)

I have the 4224, too and absolutely it will be an issue if you're running all 6 backplanes off of 1 line back to the PSU (ask me how I know).

I had a few Toshiba drives do the same thing, it was power related (too many drives on one line). So it's possible. Only the Toshiba drives would start reallocating sectors, the WD drives would just fall out of the array. If you're using splitters, try eliminating/using as few as possible

That's precisly why I'm asking - If there's a chance for 10% supply degradation year over year, that's as big if not bigger story (which I'm sure GN would like to put to the test with his PSU tester). I don't buy PSUs every year, in fact it's on the order of 2 or 3 per decade - so I don't generally hear about this kind of thing, unless it's like the Gigabyte debacle, which is why I'm asking at all. If I need to replace sooner than 5 years (I try to get whatever is the "premium" at the time), I'd like to know

Not at all, but if there's stats showing 10% yearly degradation is possible for any "reasonably well manufactured" PSU, that would cause concern for me, and I'd for sure like to know which manufacturer it is, no?

Oh, I did as soon as I read their comment - saw a lot of FUD but nothing concrete. Capacitors aging, sure - but 10% a year - that would be a BFD, I'm genuinely curious if there's a study or legitimate source I can look at. My PSU upgrade schedule would need a serious overhaul lol.

Never heard this before, have a source handy?
