Thanks to the excelent job of Thomas Sparrevohn I get 52MB/s, this is an excerpt of their comments: "Changes the DMA speed to 66 - The Controller is a 100 controller and the= disks are 100 Disks but I think the default for the controller is 66 and hence there are most likely a small initialisation difference between Linux, Ne= tBSD and FreeBSD" # diskinfo -t ad5 ad5 =2E...
