Re:Don’t Be Afraid of RAID on Sunday May 24, 2020 @10:13PM (#23297060)
It's because ZFS is much more than RAID. RAID just exposes a disk to the OS. ZFS exposes a filesystem and knows more metadata, e.g. the checksum, so it knows when to repair the data using the redundancy from the disks.

Re:PID Theory Explained (2011) on Friday May 22, 2015 @10:42PM (#9591812)

Linear feedback controls is a complex but complete theory and it would take at least a semester at a university to understand the theory behind time and frequency domain design and the effects of discretization.
