I had an idea to install a couple of SATA III cards in my Mac Pro, then run SATA cables up to the DVD drive mounting area and mount 4 SSD drives and configure in a RAID 0 array, to get a huge amount of throughput (I figure about 1.2-1.5GB/sec) for a video editing system (I'd still keep at least one drive on the native SATA controller for booting and software installation). Unfortunately, I can't figure out how to get cables to there. I can reuse the two cables intended for the removable media drives, but I'll still need two more (I can split the power connectors - SSD drives don't use much power). Everywhere I've looked, tolerances are too tight to run anything thicker than a superthin wire with no connectors through there, at least not without cutting the chassis, which I'd like to avoid. Yes, I could get eSATA cards instead, and use external drives, but that lacks finesse. Anyone ever do this? ETA: Figured it out. The opening for the original SATA cables is a lot larger than I originally thought. If you push the mesh-wrapped cable towards the rear of the case, there's enough room to run a couple of SATA cables with connectors. Still curious if anyone's done it before, though.
