San Disk Cruzer - File Transfer Speeds

File Transfer Speeds

USB flash drives usually specify their read and write speeds in megabytes per second (MB/s); read speed is usually faster. These speeds are for optimal conditions; real-world speeds are usually slower. In particular, circumstances that often lead to speeds much lower than advertised are transfer (particularly writing) of many small files rather than a few very large ones, and mixed reading and writing to the same device. In a typical well-conducted review of a number of high-performance USB 3.0 drives, a drive that could read large files at 68MB/s and write at 46MB/s, could only manage 14MB/s and 0.3MB/s with many small files. When combining streaming reads and writes the speed of another drive, that could read at 92MB/s and read at 70MB/s, was 8MB/s. These differences differ radically from one drive to another; some drives could write small files at over 10% of the speed for large ones. The examples given are chosen to illustrate extremes.

Famous quotes containing the words speeds, file and/or transfer:

    An honest tale speeds best being plainly told.
    William Shakespeare (1564–1616)

    While waiting to get married, several forms of employment were acceptable. Teaching kindergarten was for those girls who stayed in school four years. The rest were secretaries, typists, file clerks, or receptionists in insurance firms or banks, preferably those owned or run by the family, but respectable enough if the boss was an upstanding Christian member of the community.
    Barbara Howar (b. 1934)

    I have proceeded ... to prevent the lapse from ... the point of blending between wakefulness and sleep.... Not ... that I can render the point more than a point—but that I can startle myself ... into wakefulness—and thus transfer the point ... into the realm of Memory—convey its impressions,... to a situation where ... I can survey them with the eye of analysis.
    Edgar Allan Poe (1809–1849)
