Bizarro-Moore’s Law for SSDs?

by Otaku-kun on February 17, 2012

It looks like SSDs are going to get worse over time, unlike hard drives:

SSDs are seemingly doomed. Why? Because as circuitry of NAND flash-based SSDs shrinks, densities increase. But that also means issues relating to read and write latency and data errors will increase as well.
[…]
The group discovered that write speed for pages in a flash block suffered “dramatic and predictable variations” in latency. Even more, the tests showed that as the NAND flash wore out, error rates varied widely between devices. Single-level cell NAND produced the best test results whereas multi-level cell and triple-level cell NAND produced less than spectacular results.

This suggests to me that SSDs are never going to break out of the boot-disk niche for hardware builds. I get equivalent read-speads on my striped hard drives as my boot SSD, for that matter.
