1) 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.
2) 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.
3) 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.
4) Chipset support PCIe Bifurcation: Intel Platform X299, C422, C621, Z390, Z370, Z490, Z590, Z690, X99； AMD Platform: TRX40, X399, X570, X470, B550, B450, Z590, etc.
5) To splitter PCIe in BIOS, setup X4X4 mode for X8 bandwidth allocation lane, or setup X4X4X4X4 or X4X4X8 mode for X16 bandwidth allocation lane. Note: X8X4X4 mode will not work.
6) 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: does not support M.2 SATA SSD (Key-B).
7) 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
1) 2 x M.2 PCIe 4.0/3.0 RAID Controller Adapter without PCIe Bifurcation function
2) 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
3) Soft RAID Configuration (Span, Stripe, Mirror Mode) in Windows or Mac, is not hard RAID.
4) Asmedia 1182e chip, the heatsink on-chip for heat dissipation
5) PCIe 4.0 X8 bandwidth at max
6) Support 2230/2242/2260/2280/22110 size
7) Regular profile bracket and low profile bracket
8) Note: to reach PCIe 4.0 speed, your motherboard, CPU and M.2 SSD should all support PCIe 4.0
How to judge whether the motherboard supports the PCIe Bifurcation function？
Two ways to judge the motherboard supports the PCIe Bifurcation:
1. Chipset:
a) Intel platform: X299、C422、C621、Z390、Z370、Z490、Z590、Z690、X99
b) AMD platform: TRX40、X399、X570、X470、B550、B450、Z590
Noted: Except for the PCI-E lane for the GPU, make sure the available PCI-E lane support PCIe splitting.
2. BIOS setting
a) If allocation PCIe lane is X16 bandwidth, please setup X4X4X4X4 or X4X4X8 mode
b) If allocation PCIe lane is X8 bandwidth, please setup X4X4
Noted:
1) Different motherboards have different PCIe splitting settings, you can check the motherboard manual before operation. Or you can consult us via Amazon.
2) X8X4X4 mode can not recognize 2 M.2 PCIe SSD, please setup X4X4X4X4 or X4X4X8 mode
