Per gb price of ram is now almost 50% higher than during the peak of COVID price spike that lasted just 3 months. I’m comparing the current gen at the time - ddr4 during COVID vs ddr5 now

Much longer than that. There was a spike in 2021 that brought high end 2x8gb ddr4 kits to about $180-200 but that’s still significantly less than what you pay for decent ddr5 now. I think you’d have to look to back to early DDR3 or even further to DDR2 prices to get higher per gb amounts.

SSD prices were this high briefly (2-3 months) mid-2021. Before that you’d have to look all the way back to times where 1tb was the largest consumer grade SSD you could buy
