4 Ports PCIe SATA 6Gbps Controller Card, PCI-E to SATA III Expansion Adapter with Cooling Heat Sink, Internal SATA 3 Converter Board for Desktop PC Hard Drives

This PCIe to SATA III expansion controller card comes with four independent SATA 3 ports, each supporting up to 6Gbps transfer speed, greatly expanding your desktop computers storage connection capacity. It is an ideal solution for users who run out of native motherboard SATA ports when installing multiple solid state drives, mechanical hard disks or optical drives.

Equipped with an aluminum heat sink covering the main control chip, this adapter effectively dissipates working heat and avoids overheating failures during long-time high-load storage read-write tasks, maintaining steady data transmission without lag or disconnection.

Adopting universal PCIe x1 bus design, the card can be inserted into PCIe x1, x4, x8, x16 slots on any mainstream desktop motherboard with no compatibility issues. It delivers stable power and signal to connected storage devices, supporting hot-swap function for convenient drive replacement without shutting down the PC.

No complicated driver configuration required for most mainstream operating systems including all versions of Windows and Linux. Simply install the card into the PCIe slot, connect SATA data and power cables to your hard drives, and the system will recognize new storage devices automatically.

Compact PCB layout saves internal chassis space, suitable for home PCs, workstations, file storage hosts and video editing equipment. If you need to add more storage space without replacing your motherboard, this 4-port SATA expansion board is a reliable and affordable upgrade accessory.
