expand on the CPU thermal slowness

| Mar 28, 2012 at 0:41 | comment | added | Adam Davis | @bmike The drive is vastly slower than the flash it's using to store bad block relocations. You shouldn't notice a difference between requesting a regular block and requesting a block that's been relocated. | |
| Mar 28, 2012 at 0:40 | comment | added | Adam Davis | @DanielL Digital processors are clock controlled by vibrating crystals, which are often rated not to change in frequemcy by more than a few millionths of their original value over 25+ years. When they do deviate, it's unnoticeable - less than 0.0001% - or results in complete failure. If anything you might get errors due to power supply problems due to dry capacitors, but things don't slow down. | |
| Mar 28, 2012 at 0:38 | comment | added | bmike♦ | To a first approximation, whatever incremental slowness is added by the fact that some proportion of the blocks are bad and the drive has to relocate them is masked by all sorts of delays up the chain. How often is the computer waiting on the drive, caches mask that delay, drive motors spin constant RPM, drive head control failures are usually catastrophic and not creeping, etc... | |
| Mar 28, 2012 at 0:36 | comment | added | Adam Davis | @KyleCronin The hard drive speed is very precisely controlled with an adaptive speed controller. It might get hotter as it become more difficult to maintain speed as bearings wear out, but it will never deviate in speed until it fails completely. | |
| Mar 28, 2012 at 0:34 | comment | added | Kyle Cronin | I suspect that the solid state components (processor, memory, graphics, etc) continue to operate at the same speed, but what about the hard drive? It's conceivable that the spindle motor or the seek head might slow down over time, no? | |
| Mar 28, 2012 at 0:33 | comment | added | Daniel♦ | I find this so hard to believe. Could my senses deceive me this much?!? Processors don't process slower when they are older? | |
