What Does Hard Disk Data Transfer Rate Mean?

The HDD Data Transfer Rate depends on the location of the track. It is higher if data store on Outer track (more data sectors/rotation) and lower if data store on inner track (fewer data sectors/rotation).

The HDD with speed 7200 rpm has 1030 Mbit/sec ‘Disk-to-Buffer) data transfer rate and ‘Buffer-to-Computer’ interface is 3.0 Gbit/sec SATA. It also depends on the computer’s file system fragmentation, rotational speed, and data recording density.

What Does Hard Disk Data Transfer Rate Mean?

The data transfer rate in a hard drive is commonly used to measure how fast data is transferred from one location to another. Like for example, a hard drive may have a maximum data transfer rate of 480 Mbps while your internet service provider may offer you a connection speed with a maximum data transfer rate of only 3 Mbps.

Data transfer rates are normally measured in bps or bits per second different from bytes per seconds which is a little bit confusing. Since there are eight (8) bits in a byte, a constant data transfer rate of about 80 Mbps is actually only transferring 10 MB per second. In hard drives, higher performance comes from devices that have better performance characteristics.
