I am looking for the best settings to have best performance on this raid array, maybe by making stripe size, block size the same.. What is the best setup for sectorsize of geli init -s ? I did not find the unit for this setting ! is it bytes ? geli init -s 65536 would be a good choice ? And for newfs, should I use a blocksize of 65536 ? newfs -O 2 -b 65536 ? Thanks Cédric
