SI-MPE40150 M.2 22x42 M-Key PCIe to 2 Port SATA III Expansion Card with Jmicro JMB582 Chipset, 6Gbps SATA 3.0 Storage Adapter for Desktop PC, NAS and Industrial Host Storage Expansion

The SI-MPE40150 M.2 22x42 PCIe to dual SATA 3.0 expansion card is a compact internal storage expansion solution designed for desktops, mini hosts, NAS servers and industrial control equipment. It utilizes the unused M.2 M-Key 2242 PCIe slot on the motherboard to expand two fully functional SATA III 6Gbps interfaces, effectively solving the problem of insufficient native SATA ports on mini ITX motherboards, small chassis and embedded devices.

Powered by mature Jmicro JMB582 controller chip, this adapter complies with PCI Express 2.0 and Serial ATA 3.0 AHCI official specifications. Each SATA port delivers up to 6Gbps bandwidth, with a maximum sequential read and write speed up to 850MB/s for dual drives. It supports FIS-based and command-based port multiplier switching, native command queuing (NCQ), hot swap and power management functions, ensuring continuous stable data transmission during 24/7 non-stop working for NAS storage and file server tasks.

Strictly designed in 22x42 M.2 M-Key form factor, the card is directly inserted into the motherboards M.2 slot without occupying external PCI-E bracket space, keeping the chassis wiring tidy and improving internal airflow and heat dissipation. The reinforced PCB circuit and gold-plated contacts greatly reduce signal attenuation and electromagnetic interference.

It features true plug-and-play operation, no complicated driver download or system configuration required. Widely applicable for DIY PC storage expansion, home NAS disk array building, video surveillance NVR hard disk expansion, industrial embedded host peripheral expansion and old SATA hard drive resource reuse, a cost-effective compact storage upgrade accessory.
