Fiber 10Gb RJ45 PCI-E ネットワークカード NIC. ## Overview The H! Fiber X540-T1 is a 10-gigabit PCI-E network card built around the Intel X540-BT2 controller. It offers a single RJ45 port and works with existing Cat.6A or Cat.6 cabling, making it a cost-effective way to upgrade to 10GbE without rewiring your home or small office. This card uses a PCI Express 2.1 x8 interface and fits into x8 or x16 slots. With a maximum throughput of 10 Gbps, it is designed for NAS users, content creators, and virtualization environments where high bandwidth and low latency matter. ## Connectivity & Compatibility Interface: PCI Express 2.1 x8 (compatible with x8 and x16 slots) Port: Single RJ45 (10GBASE-T) Cable support: Cat.6A up to 100m, Cat.6 up to 55m OS support: Windows 7/8/10/11, Windows Server 2003–2019, Linux (CentOS/RHEL/Ubuntu/Debian/FreeBSD), VMware ESX/ESXi 6/7, SLSE 11/12, and more Both low-profile and full-height brackets are included, so the card fits standard desktop PCs as well as slim server chassis. Drivers can be installed from the included CD or downloaded from Intel's website. ## Product Info Released around 2021, the H! The manufacturer provides a 1-year free warranty and lifetime technical support. Accessories include a driver CD, low-profile bracket, and full-height bracket. Market positioning is entry-to-mid-range 10GbE networking. Compared to Intel-branded X540-T2 or X550-T1 cards, this unit offers a significantly lower price point, making it an attractive option for enthusiasts and small businesses looking to experiment with or deploy 10GbE on a budget. ## Best Use Cases NAS and home server owners: If you frequently transfer large files between a NAS and multiple clients, upgrading to 10GbE eliminates the bottleneck of 1GbE. This card is a straightforward way to add a 10GbE port to any desktop or server. Video editors and creative professionals: Working with 4K/8K footage or large project files over a network becomes much faster. With 10 Gbps, you can edit directly from network storage with near-local performance. * Virtualization and IT enthusiasts: The Intel X540 controller supports SR-IOV and VMDq, which improve network performance in virtualized environments like VMware ESXi. This makes the card suitable for homelabs and small-scale server deployments. For typical web browsing, streaming, or light file sharing, 1GbE is still sufficient. Also, remember that a 10GbE switch or direct cable connection is required to achieve full speed, adding to the overall cost. ## Things to Consider PCIe slot availability: The card requires an x8 or x16 slot. Some motherboards have x4 slots that may not recognize it, so check your board's manual before purchasing. Heat management: The Intel X540 controller can run warm under load. Ensure your case has adequate airflow, or consider adding a dedicated fan near the card. Switch requirement: To connect multiple 10GbE devices, you will need a 10GbE switch (still relatively expensive) or use a direct cable between two machines. Not Intel-branded: While the chip is genuine Intel, the card itself is from H! Fiber. Firmware updates and support may differ from Intel's own adapters. For mission-critical enterprise use, an Intel-branded card is recommended. ### Product Disclosure (Amazon) - Manufacturer: H!Fiber.com - Seller: エラ⭐ ⭐ ⭐ ⭐ ⭐ - Fulfilled by: エラ⭐ ⭐ ⭐ ⭐ ⭐ - ASIN: B09MJYCXYF - Note: This article covers a manufacturer-made product based on Amazon listing details.
