I don't think most of the people who actively post on this list are into buying cutting edge hardware but are usually dealing with 2-5+ year old hardware. That said SMR should be treated more like a (Write Once, Read Many) WORM drive. If you are rewriting data to it.. it is going to be abysmal in speed and use. http://www.storagereview.com/seagate_archive_hdd_review_8tb Write performance on SMR seems to be 1/20th of PMR drives so it isn't really going to matter what the filesystem underneath is because the largest variable is the drive itself. [EG zfs might increase by 20% but not the 2000% needed to match PMR] -- Stephen J Smoogen.
