What is the Difference Between SATA and USB Hard Drives?

For those who are not familiar with their PC working they don’t know what is the difference between SATA and USB hard drive. They consider it as the same. But I must tell them that there is a lot of differences between these two…

First of all, we should know in brief what are these two.

SATA hard drive

SATA or you can say Serial Advanced Technology Attachment, is a single cable which is used to connect 2 devices from point to point.  It is a storage-interface for connecting host bus adapters to mass storage devices such as hard disk drives and optical drives. This cable helps in transferring data from your local PC to hard disk or CD ROM devices. The main advantage of using this cable is this that the transfer speed of the cable starts from 150 MBPS, which is a huge one. SATA are very thinner serial cables which facilitate more efficient airflow inside a form factor and also allow for smaller chassis designs.

USB hard drive

USB drives are those drives which connects external storage devices to your PC. USB means Universal Serial Bus which provides you 1.1 or 2.0 user interfaces. USB drives has the same work as of floppy drives. But the USB are smaller, faster and a thousand times storage capacity than floppy drives. These are portable, sleek and having compact design which makes them easy to store.


SATA drives provides higher speed than USB hard drives.


SATA is situated inside of your PC while USB is an external device.


SATA cannot be removed from your PC and taken to anywhere while you can take USB to anywhere you want.
