Topic: Data transfer rate

	What is Data Transfer Rate?
		Data transfer rate (DTR), is the speed at which data can be transmitted between devices.
		The data transfer rate of a device is often expressed in kilobits or megabits per second, abbreviated as kbps and mbps respectively.
		The RAID is forced to adopt the data transfer rate of the slowest drive so as not to lose data as it travels across that disk from faster drives.

	Internal Media Transfer Rate
		Note: Media transfer rates are not normally specified in megabytes per second, even though sustained transfer rates are; this is not 100% consistent, however.
		For this reason, the media transfer rate decreases as you move from the outer tracks of the disk to the inner ones.
		The media transfer rate of the drive is primarily affected by all of the various data recording and encoding factors, as well as the size of the platters, and the drive's spindle speed.

		Data transfer rate is the speed with which data can be transmitted from one device to another.
		The data transfer rate for a CD-ROM drive is measured in terms of bytes per second and measures the speed at which the drive can transmit data to the system’s memory and CPU for processing.
		Older single speed drives could transfer data at 150K bytes/second, the same speed as a standard audio drive; but at this speed, images were jumpy and sound output had pops and cracks in it when the drive was used to read a video file such as a Video-CD clip.

	More Details On RAID
		Data loss because of a disk drive failure can be recovered by reconstructing missing data from the remaining data and parity drives.
		The data transfer rate is limited to the bandwidth of the HBA channel.
		The data transfer rate is limited to the bandwidth of the SCSI channel.

	Internal Data Transfer Rate
		Since the obvious objective in using a hard disk is to transfer data to the hard drive and onto the disks, or off the disks and out of the drive, the rate of data transfer is of paramount importance.
		The internal data transfer rate, which is the real rate that data can be read from the disk, is often called the sustained transfer rate, while the external rate is called the peak or burst transfer rate.
		Calculating the data transfer rate is reasonably simple, provided you know the true specifications of the drive; figuring the transfer rate will show you what design parameters have an impact on this performance measure.

	data transfer rate - a Whatis.com definition (Site not responding. Last check: 2007-10-20)
		A data transfer rate (or often just data rate) is the amount of digital data that is moved from one place to another in a given time, usually in a second's time.
		In general, the greater the bandwidth of a given path, the higher the data transfer rate.
		In computers, data transfer is often measured in bytes per second.

	VALVE: Copy Data, Limiting Transfer Rate
		However, when the operation in question consumes scarce shared disc or network transfer bandwidth (for example, when copying large files between machines on a local network or across the Internet), it may be wise to limit the transfer rate to avoid degrading performance for other users or applications.
		Options permit measuring transfer rate without enforcing a limit and determining the timing granularity of the system on which the program is run.
		If the measured mean transfer rate has fallen sufficiently behind the requested rate such that no pause between blocks is indicated, valve normally skips the pause.

		The acquisition memory is the high speed memory that captures the data from the analog to digital converters.
		If an LSA1000 is armed and trigger occurs while it is in the middle of transferring a waveform over Ethernet, the new data will sit in the acquisition memory until the processor is finished with the current transfer.
		After finishing the Ethernet transfer, the processor will see that the acquisition is finished and immediately copy the new data into system memory.

		(Or "throughput") The ammount of data transferred in one direction over a link divided by the time taken to transfer it, usually expressed in bits or bytes per second.
		Where data transfer is not continuous throughout the given time interval, the data transfer rate is thus an average rate that will be lower than the peak rate.
		The peak or maximum possible rate may itself be lower than the capacity of the communication channel used if the channel is shared, or part of the signal is not considered as data, e.g.
