Yea, the 3.5 inch is the size of the spinning platter. You never get to see that, unless you are ready to destroy the drive.

(Geezer voice) my first hard drive was a 10 MB (not gigabyte!) 3.5 inch drive. When I upgraded to my next computer it was a full height 5.25 inch hard drive, and it was a whopping 32 MB drive. It was physically massive, but not so much for storage. (end geezer voice)

Segate technologies had a local design and hard drive plant and they were customers. One day they brought in a old 14 inch 100MB hard drive the size of a power washer. They had a large box of high density 5.25 inch floppies and their new state of the art 1GB 3.5 inch hard drive. I drooled all over it, and I could not even imaging how anyone could ever fill up a 1 gig drive.

We took a lot of pictures that showed haw many floppies it was to be a gig, next to the drive. They used the photos in their advertising and corporate publications.

I "got" to go into the clean room and take photos of the building of the drives. I can tell you hauling a tripod, Sinar S 4x5 camera and multiple sheet film holders around in there taking photos was a sweaty chore. I was in the full tyvac clean suit, gloves, mask the whole kit. I felt like an astronaut. The photos turned out great and the loved them.
