Welcome to our store! We are introducing our latest product, the SA3004 expansion card. This card boasts several key features that ensure optimal performance and compatibility with your system. Firstly, the rear SATA3.0 interface has been upgraded to include four interfaces, making it more suitable for tight spaces and providing better stability in 2U chassis. Additionally, the rear cables will no longer cross over with the graphics card, ensuring a clean and efficient installation. This product is designed to be compatible with both 4U and 2U chassis, thanks to the included dual fixed brackets. Whether you have a large or small chassis, this expansion card will fit perfectly. To enhance heat dissipation, we have integrated a larger heat sink. This ensures better cooling performance, making it suitable for long working hours without thermal issues. Installation of the SA3004 is straightforward, thanks to the PCI-E interface with a thick gold-plated contact. This not only provides better contact but also ensures smooth data transmission, effectively reducing data loss. Furthermore, the card's rear design is smooth, minimizing the risk of blocking the graphics card fan and improving overall ventilation. In addition to these features, the SA3004 expansion card incorporates a four-layer PCB with an insulating layer in the middle. This design enhances its anti-interference capability, ensuring stable and reliable performance. The card also offers multiple mode selections, including AHCI, IDE, and data disk modes, providing versatility and flexibility for various system configurations. The SA3004 expansion card is compatible with Windows XP/2003/Vista/Win7/Win8/Win10 (32/64 bit) operating systems. The card's dimensions are approximately 120 x 65 x 56 mm (4.7 x 2.6 x 2.2 inches), making it compact and easy to install.
