External Storage

Hey everybody,

New kid on the block. I'm manipulating huge audio files and am looking to expand my 4-drive SSD Crucial C300 RAID array. I just purchased a RocketRaid 2744 raid card capable of up to 16 drives. It has 4 mini-SAS external connectors. Right now I'm running the cables into another PC case with the drives and a separate power supply. My first question is "Is this safe?" and my second question is "Where can I get a reasonable 16-bay external storage array that will maintain Sata iii 6.0 gbps?" I've looked around and am totally confused - JBOD, eSata, USP ... and the like! It seems to me that all I need is a box with bays and a power supply, since all the logic is on the Raid card. Any help would be greatly appreciated.

Thanks,
Bruce
