Hi,
FYI my experience with original Hyperdrive:
I had an original 10MB Hyperdrive when they first came out. Friend was on holidays in the States (I'm Australian) and he phoned me and said "do you want one of these new Hyperdrives? It'll cost about $AU3500." At that time I hadn't heard of them, they weren't available in Australia.
Now my Mac itself cost less than that, so it was an expensive upgrade. But at the time the only other hard disks available were serial-connected 5MB drives, which ran like sick dogs - getting back to the Desktop from an application took minutes - it was awful.
The Hyperdrive on the other hand ran like a greased pig. (In fact years later when I got a Mac SE with internal 20MB SCSI drive, I benchmarked it at line-ball with the old Hyperdrive)
If you weren't around at the time, I can tell you the original Hyperdrive was like from another galaxy - suddenly the Mac flew - the product name was accurate, and space was not an issue, very exciting. Like jumping out of the steam age. I was literally "the envy of my friends", e.g. my brother-in-law ordered one from the US the day he saw mine.
The speed and particularly the capacity made things possible/feasible, e.g. software development. I mean imagine having to run only off one floppy drive.
The 10MB ones were intermittently unreliable (errors), we managed to get a 20MB swap which was much better, although the cost of the calls to the US from Australia and the freight added up.
Re. the cost, a 500GB bare drive today is under $100 here. That makes my first Hyperdrive about 2,000,000 times more expensive, without even calculating the present value of about $AU4000 total spent in circa 1985(?).
FYI the first Mac SCSI HD I bought (upgrading SE20) was Quantum 106MB, which cost (best price) $1600. So only 75,000 times more expensive than hard-disks today...
Eventually the 20MB crapped out and by this stage the manufacturer GCC had a local presence, and they graciously swapped me an external 20MB SCSI drive.
Hope you found that interesting, and enjoy your Hyperdrives.
