There is no definitive answer (yes or no) on whether to mirror a dedicated log device, as reliability is one of many variables. This leads me to the frequently given but never satisfying "it depends".
In a time when too many good questions go unanswered, let me take advantage of our less rigid "rules of engagement" and share some facts about the DDRdrive X1 which are uncommonly shared: - 12 Layer PCB (layman translation - more layers, better SI, higher cost) - Nelco N4000-13 EP Laminate (extremely high quality, a price to match) - Solid Via Construction (hold a X1 in front of a bright light - no holes :-) - "Best of Breed" components, all 520 of them - Assembled and validated in Northern CA, USA - 1.5 weeks of test/burn-in of every X1. (extensive DRAM validation) In summary, the DDRdrive X1 is designed, built and tested with immense pride and an overwhelming attention to detail.
