I am not so familiar with RAID, but have been doing lots of research and just wanted other opinions. http://www.bhphotovideo.com/c/product/627303-REG/PROAVIO_EB4_FR_editBOX_EB4FR_Quad_Interface.html was recommended, along with 4 of these HDD http://www.newegg.com/Product/Product.aspx?Item=N82E16822136284. This would be connected to my Quad 2.93 for video editing, mostly SD but getting involved in HDV as well. Would be a RAID 5, connected through FW800. This unit has the built in controller, so I wouldn't need anything else, correct? Does this sound good?
