This article covers Siig NN-E38012-S3 FireWire 800 3-Port PCIe [並行輸入品].

Overview

The Siig NN-E38012-S3 is a PCI Express x1 expansion card that adds three FireWire 800 (IEEE 1394b) ports to any compatible desktop PC. It's designed for users who need to connect legacy FireWire peripherals—such as audio interfaces, video capture devices, or external hard drives—to modern systems that no longer include native FireWire support. This card features one external FireWire 800 (9-pin) port and two internal FireWire 800 headers, offering flexible connectivity for both rear-panel and front-panel installations. It uses a Texas Instruments TSB81BA3 controller, known for reliable performance and broad compatibility across operating systems.

Connectivity & Compatibility

The card connects via a PCI Express x1 interface, fitting into any standard PCIe slot on desktop motherboards. It provides one external FireWire 800 (9-pin) port and two internal FireWire 800 (9-pin) headers, allowing simultaneous use of up to three FireWire 800 devices. Compatible devices include FireWire 800 external hard drives, audio interfaces, video capture devices, and digital cameras. With an optional adapter cable, FireWire 400 (6-pin) devices can also be connected, though speed will be limited to FireWire 400 rates. Operating system support covers Windows 10 and 11 using built-in or TI generic drivers. macOS and Linux are not officially supported, but community reports indicate occasional success with manual driver configuration.

Product Info

Released in the early 2010s, the Siig NN-E38012-S3 remains available as a parallel import through retailers like Japan, priced around ¥18,500 (approximately $125 USD) as of August 2025. Market positioning is squarely in the "legacy revival" niche—mid-range for its category. While its 800 Mbps transfer speed is far below modern USB 3.2 or Thunderbolt 4 standards, it's an essential bridge for users who rely on existing FireWire gear. Warranty varies by seller (typically 30-day defect coverage for parallel imports). The package includes a low-profile bracket, driver CD, and a quick-start guide.

Best Use Cases

  1. Professional Audio/Video Creators Ideal for musicians, podcasters, and videographers still using FireWire-based audio interfaces or DV camcorders. Many such devices work more reliably through a native FireWire controller than through USB adapters. Not recommended for users who have already migrated to USB-C/Thunderbolt gear. 2. DIY PC Builders with Legacy Peripherals Great for enthusiasts who want to keep using old FireWire hard drives or digital cameras with a new build. The internal headers allow front-panel port expansion if your case supports it. Avoid if you primarily transfer large files—FireWire 800's 100 MB/s ceiling is slow by today's standards. 3. Enterprise/Educational Environments Useful in labs, workshops, or studios where specialized measurement equipment or industrial cameras require FireWire connectivity. The three-port design supports multiple devices simultaneously. Not suitable for laptops or small-form-factor PCs lacking a free PCIe slot.

Things to Consider

As a parallel import, this card lacks Japanese-language documentation and domestic support—troubleshooting is user-driven. Ensure your motherboard has a free PCIe x1 (or longer) slot; a large graphics card may block access. FireWire 800's maximum throughput of 800 Mbps (≈100 MB/s) is a fraction of modern USB 3.2 Gen 2 (10 Gbps) or Thunderbolt 4 (40 Gbps). If your workflow involves frequent large-file transfers, consider upgrading to USB 3.0+ peripherals instead. ## FAQ
Q: Does this card work with Windows 11? A: Yes, Windows 10 and 11 typically recognize it with built-in drivers. In some cases, manually installing TI's official driver may be required for full stability. Q: Can I connect FireWire 400 (6-pin) devices? A: Yes, using the included adapter cable or a standard FireWire 800-to-400 adapter. Speed will be limited to FireWire 400's maximum of 400 Mbps. Q: How do I use the internal headers? A: The internal headers are for connecting to front-panel FireWire ports on compatible PC cases. You'll need a separate bracket (not included) that mounts in an expansion slot and connects via cable to these headers.
