USB or the Universal Serial Bus is the standard for wired connections today. Every modern computer comes equipped with USB ports to facilitate seamless wired connectivity.
Much before USB became the norm, there was something called the SCSI or Small Computer System Interface, which provided the same connectivity. The world slowly shifted to USB but the SCSI is not yet obsolete. There are still systems that use SCSI. However, USB ports are more practical because they have a variety of uses and also due to the fact that to use USB, you don’t have to reboot your computer.
Now, if you have a SCSI port and are wondering how to bring your computer up to today’s standards of the USB, you have come to the right place. We have put this article together to help you understand what a SCSI is and which adapters you can buy to make the switch.

A Brief About SCSI
SCSI is a controller that can link different items with one data cable. This process is called daisy-chaining. It comes with an adapter card that uses the PCI expansion slots to connect to the computer.
Over the years, SCSI evolved quite significantly. At the moment, there are quite a few types:
- SCSI-1: The original version
- SCSI-2: Introduced in 1994, there were 2 types: Fast SCSI (10 MB per second, 8-bit parallel bus) and Wide SCSI (20 MB per second, 16-bit bus)
- SCSI-3: Released in 1996 with double the data speed
- Ultra-2 SCSI: Had a data rate of 80 MB per second
- Ultra-3, Ultra-320, and Ultra-640 are the subsequent versions
There are also a few alternatives that you should be aware of here, specifically the SCSI Parallel Interface, which requires 50-pin, 68-pin, or 80-pin connectors.
Our concentration is going to be on the 50-pin connectors and adapters for the same.
