That is, until next year when prices fall even further. And the year after that, and the year after that...
Until one day you won’t even be able to GET a spinning hard drive any more.
Is anything truly obsolete if it works just fine in its intended role?
Actually like prices for RAM, prices can fluctuate much, though usually on a downward trend, but the average cost of a SSD stayed quite high for a long time before a rather dramatic drop due to over supply and other factors. Which can go up as RAM prices have during periods.
With the high prices of Nvidias RTX cards and spotty availability of more-affordable alternatives, plus the continuingly high price of RAM, falling solid-state drive (SSD) prices have been one of the few bright spots in the PC building world in 2018. As we predicted early this year, new technologies and increasing die sizes have led to lower prices. And in higher-capacity 1 and 2TB models, the falling price trend seems to be accelerating, according to data from PCPartPicker.
In 2016 and 2017 NAND and SSD prices rose due to shortages due to strong demand and limited supply. Starting in mid-2018 the shortage in NAND flash memory was satisfied and with new 3D NAND factories coming on-line and with demand for smart phones slowing, the industry moved into an oversupply situation. This resulting in declining prices for NAND flash in the latter half of 2018. There are projections that the decline in NAND flash, and thus SSDs prices, will continue in 2019, with a 10% drop in price per GB expected in CQ1 2019. DRAM memory also declined in price in the second half of 2018, with continued declines expected in 2019. https://www.forbes.com/sites/tomcoughlin/2018/12/21/digital-storage-projections-for-2019-part-1/#1fd439524428
In June [2016] the average retail price...for a 128GB SSD was $91.55; for an SSD in the 240GB to 256GB range, the price was about $165.34, DRAMeXchange's data showed. https://www.digitaltrends.com/computing/ssd-prices-fall-2019/
Now the price for a 128GB SSD is as low as 21.00 and a 240GB about $32 .
