PCIe 3.0 x4 to 5-Port SATA III 6Gbps Expansion Card with JMB585 Chipset, PCI Express SATA 3.0 Adapter with Aluminum Heat Sink for SATA HDD SSD Storage Expansion

This PCIe 3.0 x4 SATA expansion card adopts mature JMB585 control chip, expanding one PCIe slot into 5 independent SATA 3.0 interfaces, greatly increasing the number of storage access ports for motherboards lacking native SATA ports.

Every SATA channel supports SATA III 6Gbps maximum transfer rate, ideal for mass data backup, disk array assembly, video material storage and data recovery work. The attached large-area aluminum heat sink quickly dissipates heat generated by long-term concurrent reading and writing of multiple hard drives, effectively preventing overheating, lagging or drive disconnection.

The card is backward compatible with PCIe x4, x8, x16 motherboard slots, and equipped with a standard full-height PCI baffle to keep the card firmly fixed in the chassis. Separate LED lights correspond to each SATA port, clearly showing power and read-write activity status of every hard disk at a glance.

No complicated driver installation needed, plug and play for Windows and Linux systems. It is a cost-effective storage upgrade accessory for desktop PCs, small workstations and entry-level servers to expand multi-disk storage space.
