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 (tm) ). Along the way we have sought out like-minded individuals to exchange strategies, war stories, and cautionary tales of failures.

What is your test method for new HDDs before adding to array? (alien.top)

I'm looking to add some large Enterprise HDD's to my array and was wondering if a Long Smart Test would be sufficient before putting the drive into service?

I use Windows/Snapraid and have/use HDD Sentinel and also could run Read and/or write tests.

I'm curious what others testing methods are after a drive is shipped to them before putting it into service?

Don't need to. I use ceph with replication, so the drive can die after 5 mins and it wouldn't matter at all to the array. I just put a sticker on it that tells me when it's bought so I can RMA it if it dies quickly. Beyond that, I can basically lose two thirds of my drives and still be perfectly fine, or I could lose data from 3 drives failing if I'm unlucky and it's from three different servers, one of which is off site. And that loss has to be within like a couple of hours between them or it'll have time to create new replicas of it, and it will only be a small subset of the data that has priority once the second drive fails as it will only need to create new replicas of the data that only exist on those two drives which isn't going to be more than a couple of hundred megs really.

Basically, I love Ceph if that doesn't show ;P
