testdasi Posted July 29, 2020 Posted July 29, 2020 So I have a pool of 4 SSD's running in RAID5 for data chunks. It defaults to RAID1 for System and Metadata chunks. Since btrfs device allows RAID10 for 4 devices, is there any harm to change metadata (and system) chunks to RAID10 instead of RAID1? Reason: theoretically faster while same protection against single failure. Quote
JorgeB Posted July 29, 2020 Posted July 29, 2020 Should be OK, don't remember reading anything against that, though doubt you'll notice much performance difference, if any. 1 Quote
