It is a lot of change. One of my first jobs after the Navy was working with Maxtor and Seagate. Somewhere I still have a 5MB 5.25” full-size winchester drive. 5MB!
Cool! I went to a talk at IBM Almaden Valley a long time ago (around 1982) about the history of the IBM 305 RAMAC — the first disk drive. It was a celebration of the 40th anniversary of the tech.
My wife bought me a SuperMac “DataFrame” 20 MB Hard Disk for our Macintosh Plus. It was the first hard disk drive to take advantage of the SCSI port on the Macintosh Plus. She paid $600 for it at the time (almost $1,700 today!). What a sweet present! That was back in the Dual Income, No Kids days. Shortly after that our first was born and that was the end of expensive toys.
