FreeBSD-6.0 known this device. (Intel SE7320 EP2)
amrd0: <LSILogic MegaRAID logical drive> on amr0
amrd0: 1430511MB (2929686528 sectors) RAID 5 (optimal)
ar0: 76228MB <LSILogic v3 MegaRAID RAID1> status: READY
ar0: disk0 READY (master) using ad4 at ata2-master
ar0: disk1 READY (mirror) using ad6 at ata3-master

System now work with RAID

 df -h
Filesystem       Size    Used   Avail Capacity  Mounted on
/dev/ar0s1a      496M     55M    401M    12%    /
devfs            1.0K    1.0K      0B   100%    /dev
/dev/ar0s1d      496M     12K    456M     0%    /tmp
/dev/ar0s1e       67G    419M     61G     1%    /usr
/dev/amrd0s1d    1.3T     12M    1.2T     0%    /var
/dev/acd0        651M    651M      0B   100%    /cdrom

My questiin is now, how do i  test SATA RAID performance ?
Is there any tools or program to do some benchmark ?
