Looking for advices NAS for medias

[WoisWoi]

Hi !

I am doing research and hesitate between several possible configurations (a RAID 6, two RAID 6, a RAID-Z2 or a RAID-Z3).
I would have (maybe more) 16x 20TB hard drives. This will be used for video storage (movies, series, etc.).

Thanks you :)

RAID 6 is out for Free/TrueNAS, as that's hardware RAID, which is strongly discouraged. And 16 drives are too many for one vdev. So, really, your options are two RAIDZ2 vdevs, or two RAIDZ3 vdevs. I'd likely go for the former.

I know that RAID 6 is hardware RAID, but why is it "strongly discouraged" ?
Btw, I need good reading speed

What's all the noise about HBAs, and why can't I use a RAID controller?

1) An HBA is a Host Bus Adapter. This is a controller that allows SAS and SATA devices to be attached to, and communicate directly with, a server. RAID controllers typically aggregate several disks into a Virtual Disk abstraction of some sort...
