No moore's law with ssd
The electronics industry can mass produce chips in huge volumes, which used to increase capacity and reduce prices but now it the price does not seem to change much. As a technology SSDs have matured while reliability and performance have improved, sales have increased but capacity and cost have not reduced at the rate I would expect.
Why are all SSDs only available as 2.5" drives and not 3.5" drive? The 3.5" size would allow significantly more space for storage allowing larger capacity drives using smaller capacity chips.
A 500GB SSD appears to sell for around £125 but a HDD sells for less than £40, I would have thought manufacturing a hdd is more complex than an SSD.
