IBM's new Deskstar 75GXP needs less time than other models to access data. This time was measure to be 11.1 milliseconds.There are generally 4 access times listed for all hard drives on the market: Read Seek, Write Seek, Track-to-Track, Full Stroke. All 4 of the items are rated in milliseconds. Read seek is generally an average time it takes to move the head from one position on the drive to another to read data from the drive. For all of these, a lower number means higher performance.
Hummingbirds can only be found in the Americas, where we have over 330 species of them. Many of these hummingbirds differ drastically, from their size to their agility. Also, hummers flap their wings at unusual speeds. Sometimes covering more than 200 beats per second. Their wings vibrate on the upstroke and the downstroke which produces a kind of humming sound. The sound varies from species to species as does the frequency. Notably, the larger hummingbirds have less beats per second, meanwhile the smaller species have recorded up to 200 beats/sec. Hence, the beat time can be as short as 5 milliseconds.
