Over the course of my time selling imaging hardware, i.e. scanners, many customers ask me which is better…SCSI or USB 2.0? Actually some don’t even ask, they insist that SCSI (small computer system interface) is still the fastest option. Unfortunately for them, almost all scanner manufacturers have moved to using a USB 2.0 interface as option on their scanners and some are USB 2.0 exclusively.
When the first USB (Universal Serial bus) it was slower than SCSI and at times Flakey. Anyone who has ever installed a SCSI device knows that there was definitely room for improvement in this technology as well. Between double checking SCSI ID’s and triple checking the Termination you could spend quite a bit of time sorting out a SCSI install if it didn’t go right the first time. But when USB 2.0 came out it was stable and fast. In fact there is little to no degradation in speed with the scanners. In fact, Kofax has stopped manufacturing SCSI cards all together. VRS used to be a limitation of USB in a production environment because it required a SCSI adrenaline board interface, but now the latest versions of VRS are more versatile and work with USB 2.0 just as well if not better than SCSI.
USB 2.0 is working its way to becoming the standard in imaging technology because it less expensive than SCSI and so much easier to work with. You also have one less point of failure with the USB 2.0 vs. the SCSI card. So for those people with the common misconception that SCSI is faster and better, I’m here to tell you that USB 2.0 is just as good when it comes to speed and less expensive for your pocketbook. It also opens up the door to using laptops.
ImageSource, Inc. offers the all of the best names in imaging hardware – Fujitsu, Bowe Bell & Howell, Panasonic, Canon– each one with their own strengths, but all equipped with the newest and latest connectivity of USB 2.0
