PCIe X1 to 2-Port SATA 3.0 Expansion Card with ASM9125 Chip, 6Gbps PCI Express SATA Controller Adapter for Desktop Hard Drives & SSD Storage Expansion

This PCIe SATA expansion card adopts mature ASM9125 controller chip to expand two independent SATA 3.0 ports via a single PCIe X1 slot, perfectly solving insufficient native SATA interfaces on motherboards.

Each SATA port reaches a theoretical transmission speed of 6Gbps, delivering fast loading and file copy speeds for mechanical hard drives and SATA SSDs. The chip features stable signal processing, effectively reducing transmission lag and disconnection during long-term continuous read-write tasks such as video storage and file backup.

Compatible with all standard PCIe expansion slots (X1/X4/X8/X16), it comes with a standard full-height metal mounting bracket for tight fixation inside regular PC cases. No complicated driver installation required for mainstream Windows and Linux operating systems, and it supports bootable system disks.

Ideal for office desktops, media editing workstations and DIY storage arrays to add extra SATA hard disk space at low cost.
