2X PH46-4 4-Disk SFF8639 U.2 NVME & SATA 2.5-Inch to PCIE4.0 X16 Split Card Hard Drive Adapter

Supports four U.2 drives (4-disk) and is compatible with both SFF8639 U.2 and 2.5-inch SATA drives — note that SATA drives require a separate SATA cable connection. The card features a ventilated (hollow) chassis for enhanced heat dissipation, designed for long-term stable operation across a wide temperature range. An LED status indicator shows drive presence and activity: a steady green light when a disk is inserted and a flashing green light during read/write operations. Connectors use a thickened immersion gold plating process on the gold fingers for firmer contact and more reliable data transmission.
