In telecommunication, data transfer rate or just transfer rate is the average number of bits, characters, or blocks per unit time passing between corresponding equipment in a data transmission system.
The Transfer Assembly Project, based at the Center for the Study of Community Colleges at the University of California at Los Angeles and headed by Arthur Cohen, is the longest-standing study focusing on statewide measures of community college baccalaureate transfer.
The Transfer Assembly Projects base for calculating transferrates is a subset of all first- time community college students (it excludes students who are not first-time students as well as those who fail to complete at least 12 units).
The trend data show a dip in transferrates in the 1980s and a rise in the 1990s (see table 1), changes that the authors attribute to overall economic conditions and the emphasis on academic (in contrast to vocational) education within community colleges.
The external transferrate is dictated primarily by the type of interface used, and the mode that the interface operates in.
External transferrate is affected by a variety of interface issues, discussed in much more detail in the section on external interface performance factors.
Since the external transferrate of a drive is usually much higher than its internal sustained transferrate, that means that the STR will be the bottleneck, and thus the factor that limits performance; the high transferrate of the interface is mostly wasted.
