Overview

The Monoprice 100335 is a straightforward 10-foot FireWire 800 cable with 9-pin beta connectors on both ends, supporting the IEEE 1394b standard at up to 800Mbps. In practical terms, that translates to sustained data transfer rates of approximately 60-80 MB/s — sufficient for external hard drives, professional audio interfaces, and video capture devices that rely on the FireWire 800 protocol. The 10-foot length sits comfortably within the 4.5-meter maximum specified by IEEE 1394b for S800 operation, so there's no speed penalty for the extra reach compared to shorter cables.

This cable is built for users maintaining legacy FireWire 800 workflows — professional audio engineers with established Pro Tools or Logic setups using FireWire interfaces, video editors with older capture hardware, or anyone with external drives that predate the USB 3.0 era. The clear jacket is a minor but practical detail, allowing quick visual confirmation that the internal shielding is intact. While FireWire 800 is a legacy interface with no future development roadmap, the devices that depend on it still perform their jobs well, and a reliable cable at Monoprice's price point makes maintaining those workflows economical.

Key Features

FireWire 800 (FireWire 1394b) is the new version of the popular FireWire interface

BETA refers to the FireWire 800 9 pin connector which is called a "beta connector

It doubles the throughput of the original IEEE-1394a FireWire interface from 400Mbps to 800Mbps

Pros & Cons

👍 Pros

  • 800Mbps bus speed doubles the bandwidth of FireWire 400, providing meaningful throughput gains for external storage and audio interfaces
  • 10-foot length offers comfortable reach for studio and desktop setups without exceeding the IEEE 1394b specification limits
  • 9-pin beta connectors on both ends ensure a secure, locking connection that won't pull loose during data transfers
  • Clear jacket allows visual inspection of internal shielding and conductor integrity

👎 Cons

  • FireWire 800 ports are absent from virtually all modern computers manufactured after 2015, limiting this cable's usefulness to legacy systems or Thunderbolt-to-FireWire adapter setups
  • 9-pin to 9-pin configuration only — cannot connect directly to FireWire 400 (6-pin or 4-pin) devices without a separate cable
  • 800Mbps throughput is significantly slower than current USB 3.x or Thunderbolt standards, making this a maintenance-tier solution rather than an upgrade path
  • No gold-plated connectors, which may result in slightly less corrosion resistance over years of use in humid environments

Frequently Asked Questions

No, not directly. This is a 9-pin to 9-pin (beta-to-beta) cable designed exclusively for FireWire 800 (IEEE 1394b) ports. To connect a FireWire 400 device, you would need a separate 9-pin to 6-pin or 9-pin to 4-pin cable, not an adapter on this cable.
The 800Mbps figure is the theoretical maximum bus speed. In practice, sustained transfer rates typically land between 60-80 MB/s depending on the connected device's capabilities. This is still roughly double the throughput of FireWire 400 and competitive with USB 2.0's practical ceiling.
Yes, provided your audio interface has a FireWire 800 (9-pin) port. FireWire's isochronous data transfer protocol is particularly well-suited for real-time audio streaming, offering consistent latency that many producers and engineers prefer over USB for multi-channel recording sessions.
At 10 feet (approximately 3 meters), this cable is well within the IEEE 1394b specification limit of 4.5 meters for S800 speeds. No signal degradation or speed reduction should occur at this length under normal operating conditions.
FireWire 800 is natively supported on macOS (all versions through macOS Monterey with appropriate hardware), Windows (XP through 10 with built-in or manufacturer drivers), and most Linux distributions. The cable itself is OS-agnostic — compatibility depends on your host controller and device drivers.
