You have essentially two choices here: * use the hardware RAID that you're currently using with Windows * use ZFS to create a RAIDZ pool The first option depends on having the right sort of support in FreeBSD. You should be able to test that by downloading a USB install image and booting from that to use the live FreeBSD filesystem. You should be able to see if your Intel RAID is recognised by looking at the boot messages and seeing what devices appear in /dev If you can see the RAID device then you should be able to delete your current Windows install and write FreeBSD onto the system in its place. Your other choice is to ignore the on-board RAID, and just have FreeBSD access each drive individually and use what the OS provides to create your disk arrays. If you want a RAID5 type of setup, then the realistic choice is to use ZFS with RAIDZ. You might find going with a mirrored pair of drives works better, or add a 4th disk and make a two mirrored pairs. You can use gmirror(8) and gstripe(8) to implement that if you don't want to go down the ZFS route.
