Sorry for the delay, I had to rearrange some stuff to repeat the tests. For me, it corrupts data with -CURRENT, -STABLE (the one which has a = backport of the mfi driver from -CURRENT) and 10-RELEASE. I noticed (I didn't check it when I ran the first tests, as data = corruption was enough of a problem) that the controller is negotiating = just 150 MB/s. Not sure if the driver is lying, though.=20 # camcontrol devlist at scbus0 target 3 lun 0 (da0,pass0) at scbus0 target 4 lun 0 (da1,pass1) at scbus1 target 8 lun 0 (ses0,pass2) at scbus1 target 12 lun 0 = (ses1,pass3) at scbus1 target 15 lun 0 (da2,pass4) at scbus1 target 16 lun 0 (da3,pass5) at scbus1 target 17 lun 0 (da4,pass6) at scbus1 target 32 lun 0 (da5,pass7) at scbus1 target 33 lun 0 (da6,pass8) at scbus1 target 34 lun 0 (da7,pass9) at scbus1 target 35 lun 0 = (da8,pass10) at scbus1 target 36 lun 0 = (da9,pass11) at scbus1 target 37 lun 0 = (da10,pass12) at scbus1 target 39 lun 0 = (da11,pass13) at scbus1 target 40 lun 0 = (da12,pass14) at scbus1 target 41 lun 0 = (da13,pass15) at scbus1 target 42 lun 0 = (da14,pass16) # camcontrol inq ses0 pass2: Fixed Enclosure Services SCSI-4 device=20= pass2: 150.000MB/s transfers, Command Queueing Enabled # camcontrol inq da8 pass10: Fixed Direct Access SCSI-6 device=20 pass10: Serial Number S1D9NEADA08547X =20 pass10: 150.000MB/s transfers, Command Queueing Enabled But I've noticed that disk transfers to one of the SSDs peak around 200 = MB/s, while they reach 400 MB/s with mps and a LSI2008 card replacing the Invader.
