Re: Can't understand why anyone would buy the 20TB drive
As far as I'm aware, SMR and storage arrays do not get on well together.
I tried putting 7 of them in a RAID Z2 array, just to see what happened. For about the 100GB or so, it worked great, then it got really slow, as in bytes per second, then it just completely keeled over and failed. Other people who tried it have reported similar things.
