My thoughts:
This is a slightly unusual drive, at least due to it's manufacturer. This may look like a Conner, but it definitely is not. The lid is stamped instead of cast, and the jumper layout on the PCB actually makes sense. Most strikingly, this drive has a rather large solenoid head lock which makes a nice clunk on spinup and spindown. I hope it comes across well in the video. These drives are pretty common, all things considered, but can get pricey for no discernible reason.
