I was the engineering lead on this project back in 2007. We developed a modular approach for future-proofing drives by allowing to swap out a connection module. This system is still being used in Seagate external drives today. I also recommended a passive cooling strategy for thermal management that allowed for fanless operation on the lower cost drives. Getting the uniform light guide to look like the renderings was really tricky. We went through several design revisions until the right look was achieved. I also built CAD databases to ensure that the external housings were free of sink and cosmetic defects.
