Would you say the same with CPUs?

Certainly, we all know Intel and AMD re-qualify their CPUs for sale at either a lower speed or fewer cores. But a defective hard drive platter is a different matter as compared to disconnecting the bad core on the die or running at a lower speed. The CPU will not have an early death. Defective drive platters may run for awhile at 5400rpm and then the drive will have an early failure if the problem with the platter is serious enough. That's the part that makes it unethical.

I simply love this whole hard drive crisis!
Just read an article that pointed out how HD crisis just gave a boost for the SSD market. Thanks to the flood it seems we will get more affordable SSDs much sooner than we would otherwise, they estimated 1$ per 1GB in late 2012.

LOL later!? can't they make it much more sooner? ohh well, 60$ for a 60GB SSD~

No proof, but when thinking about what the chinese factories do with their 7200rpm failures and I cannot envision them throwing it away just because it has too much vibration jitter to work at 7200rpm. The chinese places have fairly unethical prosperity practices in my opinion. But ethical practices just cannot compete with the low-priced seller and I can only assume that eventually the lowest common denominator pulls the other competitors down into the muck as well.

It's not the platters that dictate the drive speed. It's the electronics (both motor and drive controller) that dictate those. They cannot just slow down a 7200 drive to a 5900/5400 one because each uses different set of controllers/firmwares. Swapping boards on these won't work and will most likely destroy the motors of the drive. Also note that it's the slower drives that gets the new tech first (higher platter densities) while higher speed models get the refined tech.

This is wrong. The outer edges have higher read/write speeds since the head covers much more distance (at the same rotational speed) in this region. The reason we see less 10K models is because the platters wobble more at that speed and that causes errors. Since platter densities are higher, there would less margin for error. WD remedied the problem by releasing their 10K at a smaller form factor but the gains are getting smaller and not worth the effort. 10k drives will be sucking more power but provide less and less performance gains.
