A recent Storage Newsletter article argues that SSD prices are approaching HDD prices, and that the gap has narrowed to only a 2.7 times difference.
Upon closer inspection, though, the reader will note that this is only true at lower capacities. The narrowing price gap at lower capacities has always existed in this market. The SSD Guy was making that argument back in 2007!
This post’s graphic shows a chart from the first report ever published by Objective Analysis over a decade ago: The Solid State Disk Market – A Rigorous Look.
The point of this chart was to illustrate that, at low capacities, SSDs are cheaper, while at higher capacities HDDs provide lower-priced storage.
The concept is simple: It’s uneconomical for an HDD vendor to sell an HDD for less than some floor price. This price is somewhere between $35-50; the chart is based on a $50 floor price. That’s where the black line (representing HDD rices) flattens out.
SSDs, on the other hand, can be produced at significantly lower capacities at a price that is roughly proportional to the cost of the flash chips, so the red line continues to drop even at very low capacities. At some point an SSD becomes the cheaper alternative.
Here’s a closer look at this post’s chart:
In this chart the crossover was about 6GB. SSDs were selling for ~$10/GB back then! High-capacity HDDs became most economical at only 100GB.
Prices and capacities have changed phenomenally since then! SSDs now sell for ~$0.17/GB. HDDs still have a floor price of $35-50 in high volumes and become most economical at 4TB. At these prices any capacity lower than 200GB will be more economically served by an SSD. Above that size (500GB, 1TB) there will be some ratio that depends on the capacity. This ratio approaches 10:1 once the capacity reaches the HDD’s cheapest capacity. This would be the knee in the black line.
Let’s compare the 2007 chart to the data that Storage Newsletter provides in the article’s table. This appears in the figure below:
The 2019 and 2007 charts bear strong similarities. The black line becomes roughly horizontal at 4TB and lower capacities ($63-$76), while the red SSD line continues to drop. If the article had included data for drives smaller than 500GB we would have seen an HDD/SSD crossover, just as we see in the 2007 chart.
Some things never change.

After I published this post Zsolt Kerekes, the founder of StorageSearch, reminded me that I had published the same chart as early as June 2005 in his online journal:
Thanks, Zsolt, for reminding me of that!
Thank you for the information. The charts are very helpful.
Is it possible to add another chart that shows the trend of HD prices per GB vs SSD prices per GB over time?
Peter, You’re in luck! I have published a number of posts with HDD vs. SSD prices over time dating back to 2011:
When will SSD Prices Drop Below HDD Prices?
Big New HDDs Indefinitely Postpone SSD/HDD Price Crossover
Is an HDD/SSD Price Crossover Coming Soon?
Why SSD and HDD Prices Move in Parallel
WDC: No SSD/HDD Crossover
Hope that helps!
I picked up 4 1TB 850 EVO used for $230.
It was way worth it. one of the 4 had 13.2 TBW. The rest was around 1 TBW. It is almost parity in price for me in used markets.
Toan, Good for you!
Some people get some very good deals by scouting around. Looks like you have the knack for that!
It is weird. People are more ready to drop price on the SSD than the HDD. I cant believe the prices on HDD because used is not even worth it. Just wait on a good deal on new and it is better. HDD is not a device I would want used also.
Toan, There’s something unique going on here.
The data center SSD market has come to a screeching halt. SSD sellers are dying to get rid of their product at about any price, new or used.
HDDs aren’t under as much pressure because flash memory has become oversupplied and HDDs have not.
It’s a great time to be buying SSDs, and a horrible time to be selling them! A year ago it was the complete opposite.
