(Unlike Intel 600P) 830 model is a few years old, IIRC (I have 850s, and I think I saw 860s out in something I read probably on this list, but am not sure of it). I suspect the filesystem was created with an old enough btrfs-tools that the default nodesize was still 4K, either due to older distro, or simply due to using the filesystem that long. -- Duncan - List replies preferred.
