i've 2x 2TB RAID0 lacie quadra drives. the older gen with FW800. best i ever had. powered directly via FW800 cable and can daisy chain them together. also it's silent. there is no fan. i would like to upgrade thunderbolt drives later this fall when new MBP is released. however i didn't see any good setup as my drives. ideally i want RAID0, BUS POWERED thunderbolt drives that can be daisy-chained. the current lacie drives sucks as they need power supply. what's the point. then i might as well carry big bulky desktop drives. i need a solution that get's powered by thunderbolt. what's out there ?
