SCSI on hard drive - what does that mean?

When people talk about SCSI on a hard disk, it is not always clear what is behind it. We explain what the expression means.

SCSI for hard disk: simply explained

The abbreviation stands for Small Computer System Interface and denotes a group of standards for interfaces. When a hard drive is referred to as SCSI, it means that SCSI is used as an interface between itself and other components.

• SCSI was developed to standardize communication between different peripheral devices and to make them significantly faster.
• Via SCSI, your computer can communicate with printers, hard drives, scanners and other end devices. This flexibility has quickly made SCSI a widespread standard.
• Many SCSI hard drives were used, especially in the corporate area. They were characterized by high reliability and fast data rates.
• Nowadays, the interface is almost no longer used because it has been replaced by SAS and SATA. You can only find SCSI in old systems.

In the next practical tips, we will show you what SATA is and what the differences between an HDD and an SSD are.
