Asta [AMP]<p><span>question for tech-y storage people: I just nabbed 4 extra (used) disks with a 6 TB capacity from a place that re-sells electronics (oregonrecycles.com); I think they did some testing but obviously I dunno what to extent, and also, if it was just limited to stuff like SMART data, well...<br><br>anyway, I wanna RAID it, which is fine, but I don't know how much lifetime these have left on them. For four disks with unknown usage, should I use RAID6 or RAID10? It's not </span><i>job critical</i><span> data I'll be storing on these (mostly media and such). They'll eventually be migrated into a larger RAID array but that won't happen until I'm stable and can afford to rebuild my server so this is fine for now.<br><br>I wouldn't </span><i>mind</i><span> the better read/write performance that comes with RAID10 even though it has less parity. I suspect these disks were all used together so they might have similar wear/tear patterns; in that case, I'm wondering if RAID6's double parity actually buys me any extra life? Like, given 4 disks with the same history and a probably known disk failure rate, I'm not really clear as to whether double parity is going to make much of a difference (and that if one goes down, the others probably aren't too far behind).<br><br></span><a href="https://fire.asta.lgbt/tags/techPosting" rel="nofollow noopener noreferrer" target="_blank">#techPosting</a> <a href="https://fire.asta.lgbt/tags/raid" rel="nofollow noopener noreferrer" target="_blank">#raid</a> <a href="https://fire.asta.lgbt/tags/raid6" rel="nofollow noopener noreferrer" target="_blank">#raid6</a> <a href="https://fire.asta.lgbt/tags/raid10" rel="nofollow noopener noreferrer" target="_blank">#raid10</a> <a href="https://fire.asta.lgbt/tags/storage" rel="nofollow noopener noreferrer" target="_blank">#storage</a> <a href="https://fire.asta.lgbt/tags/nas" rel="nofollow noopener noreferrer" target="_blank">#nas</a></p>
