Yes, this is true. One reason why people complain about corrupted ZFS pools is because they have hardware which writes data in a different order than what was requested. Some hardware claims to have written the data but instead it has been secretly cached for later (or perhaps for never) and data blocks get written in some other order. It seems that ZFS is capable of working reliably with "cheap" hardware but not with wrongly designed hardware.
