The read head of the HDD still has to move across the platter(s) to read one file if it is fragmented is what he meant. God, you fucks are anal.

There is an app you can get that will fragment the HDD (can't remember the name of it but will go find it) so get that app and then run HDTune bench, then defrag the HDD and run it again.

I am not arguing with any "industry experts". I am merely pointing out errors in quotations you have copied from some unknown source. Even if the source of these comments is in fact someone with experience and a job setting up or maintaining large databases, this does not qualify him as an "industry expert". And even if he /is/ an industry expert, that does not mean he is right in every point connected to his job. Even experts get things wrong. And for any given opinion, you can easily find a dozen "experts" with different views. In summary, to make a database server fail due to fragmentation you would have to try exceedingly hard to overload and misconfigure the system, even if you use a badly designed database server on a badly designed operating system, and badly fragment the disk. Maybe it takes an "industry expert" to be able to achieve this. |
