The UGREEN HDD SATA Cable (US217) is a precision-engineered data link designed to connect motherboards and host controllers to internal Serial ATA storage devices. Whether you are installing a high-speed SSD for faster boot times or adding a high-capacity HDD for mass storage, this cable ensures your data moves efficiently and reliably. Performance is at the core of the US217. Supporting SATA III standards, it delivers data transfer speeds up to 6Gbps, which is twice as fast as SATA II. For those using older hardware, the cable remains fully backward compatible with SATA I (1.5Gbps) and SATA II (3Gbps) devices, ensuring seamless integration across different generations of hardware. Build quality is where UGREEN distinguishes itself. The cable features a tinned copper core and 26AWG wiring, which minimizes signal loss and ensures low resistance for stable transmission. To prevent the frustration of accidental disconnections during critical file transfers, both ends are equipped with locking latches that provide a secure, stable physical connection. Versatility makes this cable a staple for any PC builder. It is fully compatible with 3.5-inch and 2.5-inch hard drives, solid-state drives, and optical drives such as DVD, CD, and Blu-ray players. It is suitable for use in desktop PCs, laptops, and servers. Please note that the UGREEN US217 is a dedicated data transmission cable. It does not provide power to the drive; therefore, a separate SATA power cable from your power supply is required to operate your storage device.
