Realities of Hard Drive Fragmentation

@ 2010/02/18
We have all heard that defragmenting a hard drive (HDD) can give you a boost in performance. Is this just a an old wive’s tale or is it grounded in reality?

Ignore max speeds, concentrate on min/avg, those are more important, and there you can see that defragging does help.

also read speed of 200Mb/s is very possible on a HDD, it's what burst cache is all about

What a bs ! A +200Mb/s read speed on a regular drive. He should have noticed something was wrong with his results because the read speeds outside of virtualbox were only 80Mb/s ...
