Has anyone tried using Seagate 8TB Archive drives in their Drivepool setup?
I have a home server with about 20TB of storage -- 90% of it is used for video (mostly my blu-ray collection) and the remainder is used for music and backups of computers in the house -- currently only a small amount of important stuff is redundant. I also use a couple old 1TB drives just for PVR that are in a separate pool. I'd like to add some larger drives (probably 8TB) so that I can make the entire thing fully redundant.
I've been reading this review of the Seagate 8TB Archive drive that uses SMR:
The upshot is that read performance is excellent (probably 10x or 100x my bandwidth needs for watching movies), but due to the SMR technology the write performance drops from excellent to horrible if sustained writes are larger than 20GB. Basically it has 20GB of space it can write to quickly, and then it slowly moves that to the SMR portion of the drive -- so if you saturate the cache, it slows to a crawl. The article explains that this is horrible for a RAID array when it comes time to rebuild parity, but it is considered acceptable for non-RAID applications.
So, I'm thinking that this drive should work acceptably with Drivepool, since the write operations are just to fill the drive in the first place and then to add new blu-ray files from time to time. The good thing about the drive is it has very low power consumption and price per TB, so it would seem to be a good choice for my home server application.
