But, if you stream a large amount of data at once, you are probably more dependent on the throughput. If you write very small pieces of data to different places on your drive, you're dependent on the drive's latency ( seek time, rotational delay, and access time). Keep in mind that there's a difference between latency and throughput. Typical transfer rates are from 1-1.6 GBit/sec, and can sustain transfer rates of up to 125 MB/sec. Typical values are from 5400 to 10,000rpm. Hard disk speed is usually expressed in terms of rotational speed ( rpm or revolutions per minute), which tells you how fast the platters are spinning around inside the drive. Here's a short summary of things that can affect I/O performance. The simple example you're citing (reading/writing a fixed amount of data to a particular location on disk) isn't as realistic as you might think. *:He who writes himself by his own inscription is like an ill painter, who, by writing on a shapeless picture which he hath drawn, is fain to tell passengers what shape it is, which else no man could imagine.This is actually a pretty complicated question, and it requires an understanding of how your I/O system is set up.To make known by writing to record to prove by one's own written testimony often used reflexively.To impress durably to imprint to engrave.To record (data) mechanically or electronically.( lb) To show (information, etc) in written form.If he had written a love letter, or a farce, or a ballade, or a story, no one, either clerks, or friends, or compositors, would have understood anything but a word here and a word there. *:Thus, when he drew up instructions in lawyer language his clerks, however, understood him very well.( lb) To be the author of (a book, article, poem, etc.).( lb) To form letters, words or symbols on a surface in order to communicate.(printing, dated) To arrange (types) in a composing stick for printing to typeset.* Milton How in safety best we may / Compose our present evils.* Dryden In a peaceful grave my corpse compose.To arrange in proper form to reduce to order to put in proper state or condition.280: By trying his best to compose matters with the mullahs, he had sincerely shown that he did not seek a violent collision To settle (an argument, dispute etc.) to come to a settlement.To arrange the elements of a photograph or other picture. ![]()
