PCIe X1 to 4-Port SATA 3.0 Expansion Controller Card with Marvell 88SE9215 Chip, PCI-E SATA Multiplier Adapter for HDD & SSD Storage Expansion

This PCIe SATA expansion card equipped with Marvell 88SE9215 chip converts one PCI Express X1 slot on your motherboard into four independent SATA 3.0 interfaces, perfectly solving insufficient native SATA ports on mainstream motherboards for multi-disk storage needs.

Each port complies with SATA III 6Gbps transmission standard and backward supports SATA I/II hard drives. It works universally with all mainstream storage brands including Samsung, Western Digital, Seagate, Kingston, Crucial, ADATA, SK Hynix, covering 2.5-inch SSDs, 3.5-inch mechanical HDDs and SATA optical drives. It supports building RAID arrays, NAS storage, surveillance recording systems and large-capacity data backup workstations.

The mature Marvell 88SE9215 control chip ensures stable signal transmission even when four hard disks run simultaneously, effectively avoiding hard drive unrecognition, disconnection or slow read-write speed caused by inferior expansion chips. The integrated metal shielding frame isolates EMI noise from power supplies, graphics cards and CPUs inside the chassis to maintain long-term continuous operation.

It comes with a universal full-height metal baffle that fits all ATX, MATX and ITX standard desktop chassis without modification. Complete driver packages are provided for all versions of Windows and mainstream Linux systems. After simple driver installation, all four SATA ports can be independently identified by the system without bandwidth conflict.

It is an essential storage expansion accessory for DIY gaming PCs, video editing workstations, surveillance NVR hosts, small servers and computer maintenance stores to expand extra hard disk connection ports easily and cost-effectively.
