USD- Dual M.2 PCIe 4.0/3.0 SSD Adapter: add 2 x M.2 PCIe 4.0/3.0 SSD (NVMe/AHCI Key M) onto a single PCIe X8 add-on card, you can use 2 separate M.2 PCIe SSD at the same time. Support Intel VROC and AMD Ryzen Threadripper NVMe RAID under PCIe Bifurcation Enabled Motherboard.
- ASM1182e solution allow 2 x M.2 PCIe 4.0/3.0 SSD obtain PCIE X8 bandwidth (8GB/s with PCIe 3.0 or 16GB/s with PCIe 4.0), but only under PCIe Bifurcation enabled motherboard. Note: To reach PCIe 4.0 speed, make sure your CPU and motherboard and PCIe SSD are all PCIe 4.0 enabled. Otherwise, it would not be PCIe 4.0 speed.
- Compatible with PCIe 4.0/3.0/2.0 motherboards, and install on PCIe X8/X16 slot. Low-profile bracket and regular-profile bracket are included, so work with 2U high workstations or servers with Windows, Linux, and mac OS. No driver installation is required.
- Applicable with 2230/2242/2260/2280/22110 size M.2 PCIe SSD (Key-M), such us Samsung: 980/ 970 PRO/ 970 EVO Plus/ 970 EVO; Intel Optane SSD P1600X Series , Intel SSD 6 Series ;Western Digital: WD_BLACK SN750 SE, WD Blue SN550, WD Green SN350, etc. Note: not support M.2 SATA SSD (Key-B).
- Note: Your motherboard BIOS must support M.2 NVMe SSD, and support booting from PCIe in order to boot from M.2 NVMe SSD on this M.2 PCIe adapter.
2 x M.2 PCI-E NVMe RAID Controller Adapter Card
- 2 x M.2 PCIe 4.0/3.0 RAID Controller Adapter without PCIe Bifurcation function
- Note: PCI-E bifurcation motherboard can recognize 2 x M.2 SSD, but None PCI-E bifurcation motherboard only recognize 1 x M.2 SSD
- Soft RAID Configuration (Span, Stripe, Mirror Mode) in Windows or Mac, is not hard RAID.
- Asmedia 1182e chip, the heatsink on-chip for heat dissipation
- PCIe 4.0 X8 bandwidth at max
- Support 2230/2242/2260/2280/22110 size
- Regular profile bracket and low profile bracket
