The IO Crest SY-PEX50133 is a PCIe 4.0 x4 expansion card that adds four M.2 NVMe slots, four SATA III ports, and four USB ports without requiring PCIe bifurcation. It suits NAS builders, media-server users, and workstation owners who want to add storage and connectivity through one slot.
Recommended For
- Desktop NAS or media-server builders who need to add NVMe storage and SATA drives in one free PCIe slot, without replacing the motherboard or enabling PCIe bifurcation.
- Workstation users who keep active projects or scratch data on multiple NVMe drives and also need SATA storage and fast USB ports, with workloads that can share the card’s PCIe connection.
- Desktop PC owners short on motherboard storage and USB connections who have a PCIe x4 slot available and want to add several kinds of connectivity without a motherboard upgrade.
- Users who want to attach high-speed external drives and peripherals alongside internal storage, and can connect the card’s required 6-pin power cable when using high-power USB devices.
