️ Important Note (Read Before Purchasing!)

The motherboard must support PCIe Bifurcation (splitting): This is a prerequisite for using this product. If your motherboard does not support this feature, or if the lanes are set to Auto, only one SSD will be recognized.BIOS Settings: You need to manually set the lane configuration of the corresponding PCIe x16 slot to [x4x4x4x4] mode in your motherboard's BIOS settings.Compatible Motherboards: Mainstream brands such as MSI and ASUS are supported. Please consult your motherboard's manual before purchasing to

confirm that it supports PCIe splitting.Full Link Support: To achieve maximum speeds, the CPU, motherboard, expansion cards, and SSDs must all fully support PCIe 5.0.

JEYI PCIe 5.0 X16 Quad M.2 Expansion Card-4-Bay NVMe RAID 0/1/5/JBOD 512Gb/s Speed Supports up to 8TB per SSD compatible with PCIe 4.0/3.0

Extreme Speed: Utilizing the latest generation PCIe 5.0 technology, the theoretical bandwidth reaches up to 512Gbps. Measured speeds exceed 40,000MB/s in RAID 0 mode, and single-drive read speeds exceed 10,000MB/s.Massive Storage: Up to four M.2 2280 NVMe SSDs can be installed simultaneously. Each SSD supports up to 8TB of storage, for a total capacity of an astonishing 32TB.️ Flexible Configuration: Supports multiple RAID modes, balancing speed and data security.
