This article covers Intel 82599ENチップ搭載10Gb PCI-E NICネットワークカード.
The QINIYEK X520-DA1 is a 10 Gigabit Ethernet PCI Express network card built around the Intel 82599EN controller. Featuring a single SFP+ port and a PCI Express v2.0 x8 interface, it provides an affordable way to add 10GbE connectivity to NAS, hypervisors, or small business servers. The card ships with both low-profile and full-height brackets, making it compatible with a wide range of chassis. Power consumption is just 4.8W, drawn entirely from the PCIe slot, so no extra power cable is needed. A driver CD is included, and support extends across Windows Server, Linux, FreeBSD, EFI, and UEFI environments.
Interface: PCI Express v2.0 x8 (works in x16 slots)  Port: 1x SFP+ (compatible with 10G SFP+ modules, DAC, AOC cables)  Supported OS: Windows 7/Server 2008 R2/2003, Linux (RHEL 4.8, SLES 11 SP1, stable kernel 2.6), FreeBSD 8.0, EFI 1.1, UEFI 2.1  Includes driver CD for easy setup; up-to-date drivers can also be downloaded from Intel’s official site. * Half-height and full-height brackets included for flexible physical installation.
This card is a third-party NIC that mirrors the Intel X520-DA1 design using the 82599EN chipset, offering a cost-effective alternative for the mid-range market. It is especially suited for homelab enthusiasts and small business environments where budget matters. The package includes a driver CD and brackets; SFP+ optics are sold separately. Warranty is 1 year with lifetime technical support. Compared to genuine Intel X520-DA1 or Mellanox ConnectX-3 adapters, the QINIYEK X520-DA1 delivers comparable performance at a significantly lower price point, making 10GbE more accessible.
Homelab enthusiasts building a 10GbE network for NAS, Proxmox, or vSphere clusters – this card offers Intel chipset reliability without the Intel price tag. Small business server upgrades – boosting file server or backup server bandwidth to handle multiple client connections smoothly with a single-port 10GbE link. Creative professionals with high-bandwidth NAS workflows (4K/8K video editing) looking to eliminate network bottlenecks. Note that a compatible 10GbE switch and SFP+ transceivers are required. Who should skip this – users needing dual-port redundancy or the latest PCIe 3.0/4.0 throughput. Also, single-port may be limiting if future expansion is planned.
