PCIe 3.0 expansion card with ASM1064 controller provides four SATA 3.0 ports and extends storage capacity from the PC host to an M.2 Key M slot. Key features and benefits PCIe 3.0 x2 bandwidth for stable, fast data transfer Realizes the PCIe 3.0 x2 bandwidth to efficiently move data between the PC host and the four SATA 3.0 ports. Four SATA 3.0 ports powered by ASM1064 speed and reliable transmission using the ASM1064 chipset, offering four independent SATA 3.0 connections. M.2 M Key compatibility Designed to align with the M.2 M Key standard, enabling expansion from a PC host to an M.2 Key M slot. Plug and play No software installation or driver setup required; install and start using the expanded storage immediately. Functional and simple expansion Extends the PC host to four SATA 3.0 drives via a PCI Express interface, enabling greater storage capacity from a single card. Clear, motherboardfriendly design Standard PCIe expansion card form factor suitable for compatible desktops and motherboards. Compatibility and use cases Compatible architecture Works with PCIe 3.0 capable systems and is designed to operate with M.2 M Key compatible slots. Use scenarios 1) Media server or home theater PC: add four SATA drives to store large media libraries while keeping the main storage organized. 2) Small form factor workstation or compact PC: expand storage capacity without adding multiple PCIe devices. 3) Data backup and archival setup: create a compact, fourdrive SATA expansion to manage backups or archival data. Notes This card provides a fourport SATA 3.0 expansion via a PCIe 3.0 interface, using the ASM1064 controller, and connects to an M.2 Key M slot in accordance with the M.2 M Key standard. No additional software installation is required.
