Reading the MD features I noticed there are several possibilities to create a mirror. I was wondering which one offer the best perfomances and/or what are the compromises to accept between the different solutions. One possibility is a classic RAID-1 mirror. Another is a RAID-10 far. There would also be the RAID-10 near, but I guess this is equivalent to RAID-1. Any suggestion on which method offers higher "speed"? Or there are other possibilities with 2 HDs (keeping the redundancy, of course)? Thanks a lot in advance, bye, -- piergiorgio
