Why do SSD drives get so much more expensive as they get larger? [closed]
Normal HDD costs go up very little as drives get larger. For example, an average 1TB drive costs a little under $90, 2TB costs a little over $100, and a 3TB drive costs close to $150. For HDDs, the cost per GB goes down as the number of GB goes up.
SSD costs don't work like this: a 128GB SSD goes for $120ish, 256GB goes for $250ish, and 512GB drives get up to $600. The cost per GB goes up as the number of GB rises.
What is it about SSDs that makes them so much costlier as they get larger?

I already pointed you to the great video SQL on SSDs: Hot and Crazy Love from which I will also draw my answer.
The cost of an SSD isn't so heavily tied to the actual storage media, but to the parts that manage that storage. Larger SSDs require more sophisticated controllers to be able to address that storage.
