My dad and I replaced a 100MB HDD with a 1GB HDD for $100. When did this happen?

In a very early memory and the start of my obsession with computers, my father upgraded his 100MB hard drive with a 1GB drive for $100 USD. I remember everything about that moment such as the smell of a room packed electronics, how excited my dad was to get what seemed like an inconceivable amount of storage (694 floppies, I remember doing the math), and the exact purchase price and size, $100 and 1GB.

The only thing I don't remember is when this happed. I can't ask my father unfortunately but would love to place this event in time. I remember it was very notable that 1GB could be bought for as low as $100 and it happened at a small local PC sales and repair store located in the US South. 1995 maybe?
