The Quantum Lightning 730MB drives were the tipping point for me — likely around
1994/1995? They were readily available for just under AUD1/MB for the 50-pin narrow
SCSI-2 version. I bought heaps of them, and still have maybe half a dozen spinning

I remember in 1990 we got our first 1Gig drive, I paid $1000 for it. ($1/MB).
One of the sales guys I worked with had a unit of storage called the “Costco Terabyte.”
How much one terabyte of storage costs at Costco.
When we started tracking it, it was around $5000. It was down about $40 last I

P.S. In 1990, we filled a dumpster with 9-track
tapes that we had to
abandon because of our move to new hardware that lacked such a drive,
and because our new disk system had insufficent disk space to preserve
I have since regretted that decision many times, because a lot of
stuff was lost forever.
The maximum capacity of 6250-bpi 9-track tapes was about 100MB to
170MB. A thousand such tapes would have needed just 100GB to 170GB,
an amount of space that I can now buy in Utah for about US$4 (based on
a local store offering of $94 for a 4TB USB-3 attached disk about the
size of a paperback thriller).
Sure, but how much would 170GB of storage have cost in 1990? And what would have been
the cost to mirror it, or to back it up on to a more modern tape format? Was that data
really worth tens of thousands of dollars?
