I am archiving a vast amount of media files that are rarely accessed. I’m writing large sequential files, at peaks of about 100MB/s.
I want to maximise storage space primarily; I have 20x 18TB HDDs.
I’ve been told that large (e.g. 20 disk) vdevs are bad because resilvers will take a very long time, which creates higher risk of pool failure. How bad of an idea is this?
Draid was released just a month after I built my last raid set with vdevs. Really hoping there’s an in-place migration path someday, assuming nobody finds any bugs in the next couple years.
