Kozierok  In this section I take a look at some of the more important hard disk specifications relevant to positioning performance. These include several very well-known and widely quoted specs, along with some specifications that are a bit more obscure but often just as important. Note that these specifications are not listed in any particular order. (OK, I did put seek time first since it is so important and interesting to talk about. ) Next: Seek Time
