Overview

The Monoprice 100781 is a 10-foot straight-through SCSI cable featuring 50-pin D-Sub (DB50) male connectors on both ends, designed to provide reliable data connections for legacy SCSI storage devices and peripherals. With a 1:1 pin configuration, each pin on one connector maps directly to the corresponding pin on the other, ensuring straightforward compatibility with SCSI-1 and SCSI-2 devices including hard drives, tape drives, scanners, and external storage enclosures that use the DB50 interface. The 10-foot length provides practical reach for connecting devices within server rooms, workstation setups, or equipment racks without requiring extension cables.

While the SCSI interface has been largely superseded by SAS, SATA, and USB in modern computing, many specialized and industrial systems still rely on SCSI connections for critical operations. This cable addresses that ongoing need with a simple, well-constructed design at a competitive price point. The white cable jacket aids in visual identification when tracing connections through dense cable runs. As with all SCSI installations, proper bus termination at both ends of the chain is essential for reliable operation and must be managed separately from this cable.

Key Features

Monoprice brings you a wide assortment of classic SCSI (Small Computer System Interface) cables for your legacy storage devices

SCSI was once the de facto standard for high performance systems due to it's faster transfer rates and versatility over the more standard ATA interface

Unfortunately do to it's popularity and failure to standardize on a single connector type a wide variety of cable types exist

We carry cables for many of the most popular configurations

This cable is a straight through patch cable that features 50 pin D Sub DB50 connectors

Pros & Cons

👍 Pros

  • Straight-through 1:1 wiring provides a direct, reliable connection without pin mapping concerns.
  • 10-foot length offers ample reach for connecting devices in server racks or workstation setups.
  • DB50 male-to-male configuration fits the most common legacy SCSI cabling requirement.
  • Affordable option for maintaining or extending the life of legacy SCSI hardware.
  • White cable jacket makes it easy to identify and trace among other cables in a setup.

👎 Cons

  • The 50-pin DB50 connector is limited to older SCSI-1 and SCSI-2 devices and does not fit newer SCSI standards.
  • At 10 feet, the cable approaches the practical length limits for SCSI signal integrity without active termination.
  • No built-in termination, so proper SCSI chain termination must be handled separately.
  • The cable serves a niche legacy market with a shrinking number of compatible devices still in active use.

Frequently Asked Questions

This cable uses 50-pin D-Sub (DB50) male connectors on both ends for a straight-through, pin-to-pin connection.
This is a straight-through (1:1) patch cable, meaning each pin on one end connects directly to the corresponding pin on the other end.
The cable is 10 feet (approximately 3 meters) long.
DB50 connectors are commonly found on legacy SCSI hard drives, tape drives, scanners, and external storage enclosures that use the SCSI-1 or SCSI-2 interface.
This cable supports standard SCSI and SCSI-2 transfer rates associated with 50-pin DB50 connections. It is not designed for Ultra-Wide or later SCSI variants that use 68-pin or 80-pin connectors.
