Who are we?

We are digital librarians. Among us are represented the various reasons to keep data -- legal requirements, competitive requirements, uncertainty of permanence of cloud services, distaste for transmitting your data externally (e.g. government or corporate espionage), cultural and familial archivists, internet collapse preppers, and people who do it themselves so they're sure it's done right. Everyone has their reasons for curating the data they have decided to keep (either forever or For A Damn Long Time). Along the way we have sought out like-minded individuals to exchange strategies, war stories, and cautionary tales of failures.

We are one. We are legion. And we're trying really hard not to forget.

Any affordable cases that can hold 14 HDDs and 3 SSDs? (lemmy.world)

My unRAID server has 12 data drives, 2 parity drives, and 3 SSD cache pools. Plus dual Xeons on a SuperMicro ATX board.

I currently have the Deep Silence 5 case by Nanoxia. But things are cramped. I've filled all the standard drive bays, plus put in a 4-bay 5.25 enclosure. But I still have one of the SSDs just floating around.

What would a better case to put all this stuff in?

I'm putting this here because I couldn't find a good summary anywhere else on the Internet:

There hasn't been much work on this recently, but a summary of the scholarly work in this field can be found between these sources:

Failure trends in a large disk drive population (2007)
- Findings: annual failure rates seem to not depend on temperature at all between about 30°C and 45°C, with failure rates increasing both above and below that temperature range.
Datacenter Scale Evaluation of the Impact of Temperature on Hard Disk Drive Failures (2013)
- Findings: annual failure rates seem to scale linearly with average drive temperature, roughly doubling from 5% at 32°C to 10% at 43°C. Variation in drive temperature seems to have a small, but negligible, negative effect.
Hard Drive Temperature—Does It Matter? (2014)
- Findings: Temperature seems to have no effect on annual failure rates, but average temperatures of drives in study were between 21°C and 31°C, so their conclusions are not that helpful.

The 2013 paper unfortunately is stuck behind a paywall, but message me if you would like to read it.

My suggestion given the work in the field would be to keep temperatures around 30°C if you can because at higher temperatures, you could be reducing the lifespan of your drives.
