All you can do with the web frontend can be done this way, too. Performance of the 3ware 8506 is pretty reasonable (I got a data rate of ~ 80 MB/s with RAID 10 , 55-60 with RAID 1 ) and about the same for reading and writing. Unfortunately, after my experiences (see above), i have some serious concerns regarding data integrity, though ...
