This still makes me laugh when I think about it, the cost of HDD storage over the past 30 years.

I've been in IT since 1993 (Jeez how did that happen, feels like yesterday I was managing my BBS in my room at my parents house with my 14,400 US Robotics modem, DOS 5.0, Renegade BBS and a lot of figuring things out by trial and error).

My first real modern hard drive I had purchased (in 1991) was a Parallel ATA Maxtor 340MB Drive for $300 before tax. Thats $0.88 cents per megabyte. Which at the time, was a good deal. My buddy was a baller and bought a Western Digital 1080MB Hard rive (He had a gig!!!) for $1000, and I was so jealous.

About a year ago I updated my home NAS to some 18TB Seagate Exos drives, they were $250 each.

$250 for 18TB
$13.88 per TB
$0.01388 per GB (assuming 1000 GB per TB for simple math)
$0.00001388 per MB (assuming 1000 MB per GB for simple math)

So 88 cents today buys you 63.4 gigabytes

1991 - 88 cents - 1 Megabyte
2025 - 88 cents - 63,400 Megabytes18000000

But it gets even more hilarious to me.... that 88 cents in 1991 actually = $2.07 in 2025.

So.... 1991 - 88 cents = 1 megabyte
2025 equivalent is $2.07, which = 150,000 megabytes

In 34 years technology has advanced (at least in this overly simplified and totally unrealistic metric and only specific to spinning disk storage)........ 14,999,900%

Disclaimer: I very likely Michael Bolton'd (from Office Space) that math, but even if I am off by a few zero's still staggeringly hilarious to me.
