From the article: "In a world where SSDs have become more and more common, one might ask what the point of even developing newer and bigger HDDs is." Solid state drives still cost about 10 times more per gigabyte. I'm just a web developer, but a spinning-disk drive looks 100 times more complicated to me to manufacture. I know at the beginning that hard drives would be cheaper, simply because SSDs were newer, and ther…
The big difference is that the overall performance of spinning disks is not much different than what it was 10 years ago. However, a best-in-class 2018 SSD is an entirely different beast than a 2008 model. They are somewhere around 5-30x faster now with significantly better write endurance, wear leveling, and capacity (you can get up to 4TB in consumer models for reasonable prices). The market hasn't pushed for solid…
Thats because 2008 to SSDs was like 1982 to HDDs. If you look at 2011 both of your promises are false. SATA SSD in 2011 was as fast as SATA SSD in 2018, but with about 10x more endurance.
The technology to produce crappy SSD is there, but it will "forget" its contents in couple of months when kept unplugged, or burn thru erase cycles in a year while sitting idle, just keeping content alive.
