I’m thinking that probably was around the late ’94 end, as I have this unforgettable memory of a work conversation around a just-arrived computer parts catalogue and my co-worker noticing the 1GB drives had just hit $999 for the first time. This would have been sometime in mid ’94, just before I joined the desktop services group to replace said co-worker right before he left for grad school. (I have no idea what the price difference at the time would have been between SCSI and ATA buses.)
His specific, notably excited quote, which I’ve recalled every time since, whenever I look at cost-per-storage unit: “Wow, hard drive storage is now down to a dollar per megabyte!” What I remember, as he said that, was that amounted to ~750 floppies (which at the time would have cost much more than $999 — how much, I no longer recall). All these years later, I forget his name, but I remember his hair (long, wavy, brunette) and how he drove a VW minibus (“Split windows, like what I drive, are just better,” he’d insist; I’d be all, “Sure OK I guess?” Like I knew anything about VW minibuses!).
Of course, nowadays, the cost-per-storage unit is usually around the gigabyte which, even so, amounts to mere pennies — contrasted against what was, in effect, one grand per gigabyte in mid ’94. That’s what really puts the cost-per-gigabyte into perspective from that long-ago conversation. 🙂
