Do you know what data transfer rate is?

This article will give you a brief introduction about data transfer rate and its classification.

Data transfer rate is an important indication to measure hard disk performance.

data transfer rate

It can be divided into external transfer rate and internal transfer rate.

External transfer rate is commonly called burst data transfer rate or interface transfer rate.

It refers to the speed of outputting data from the hard disk cache.

Internal transfer rate is also named maximum or minimum sustained transfer rate.

It refers to the speed of reading and writing data of hard disk on the disc.

1.Definition

Data transfer rate is an important parameter to measure the speed of hard disk.

It is measured by transmission of bytes per second (MB / s).

At present, the highest speed ofIDEinterface is 133 MB/s while forSATA, the speed has reached 600 MB/s.

2.Classification

Data transfer rate includes external transfer rate and internal transfer rate.
