Seagate 8tb archive drive as parity and storage

[Glimmerman911]

I am designing a new media storage server for a friend, and want to use solely 8tb seagate archive drives, but am reading concern about the cache and large writes.

 

When I initially populate his server, I will be pushing many terabytes of data and exceeding the cache size for sure, which some have reported as 25gb.

 

Is this going to crash or cause issues?  How can I get around any issues this will cause?  If the speed slows to 10MB/s on the initial data load that isn't acceptable either.

The worries about these drives have been largely dispelled by testing done by users here.  The general consensus at present is that these drives are a good fit for unRAID use.

That is great news, thank you!

 

I will be upgrading my server in the near future too, these drives are such a cost-effective solution and I am at the max my case can hold at 22 drives + cache!

no idea where you got that idea on the limit on cache size.  The limit is the size of the drive you decide to assign as the cache drive.

He's referring to the integrated PMR cache on the Seagate SMR drives that is used to negate the write penalties for "less than full band" writes, not to unRAID's cache drive functionality.

Ah Ok!
