Dual Slot M.2 NVMe PCIe 3.0 X4 Adapter Card with ASM 2812 PCIe Bifurcation Function, Work with None PCIe Splitter Function Motherboard

Dual M.2 PCIe SSD Host Adapter:
add 2 x M.2 PCIe (NVMe/AHCI) SSD (M-Key) onto a single PCIe X4 host adapter, allow 2 x M.2 PCIe 3.0 SSD shares PCIE 3.0 X4 bandwidth (32Gbits/s = 4GB/s at max). So you can access 2 x M.2 PCIe SSD individually, or setup soft RAID in windows/Mac/Linux/3rd party software.

M.2 PCIe RAID in Intel/AMD/Mac:
Support M.2 NVMe SSD RAID-on-CPU (VROC) in Intel Platform, but you need to purchase Intel VROC license by yourself. Support M.2 NVMe RAID in AMD Platform. Support Mac Pro 5.1

With pcie splitter function in this host adapter (ASMedia ASM2812 chip), so PCIe Bifurcation function is not required for your motherboard. That means all most of motherboards can work with this Dual M.2 PCIe SSD Host Adapter

Please make sure BIOS/UEFI support native NVMe and OS boot from PCIe lane, then this Dual M.2 PCIe SSD Host Adapter support OS boot from M.2 PCIe SSD or M.2 PCIe RAID

Compatible with PCIe 3.0/2.0 motherboards, and install into PCI-Express X4/X8/16 lane. For PCIe 4.0 SSD, it will downgrade to PCIe 3.0 level

Work with 2230/2242/2260/2280/22110 size M.2 PCIe SSD (Key-M), such as 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)

Accessaries: Full and low profile bracket, 2 x M.2 Screws and Standoffs, Screwdriver

Dual M.2 NVMe SSD Host Adapter with PCIe Bifurcation Function

• Add 2 x M.2 NVMe SSD (M-Key) onto a single PCIe X4 host adapter, so you can access 2 x M.2 NVMe SSD at the same time
• Support soft RAID in Windows/Linux/3rd party software
• Support M.2 NVMe SSD RAID-on-CPU (VROC) in the Intel Platform, but you need to purchase an Intel VROC license by yourself
• Support M.2 NVMe RAID in AMD Platform
• Support Mac Pro 5.1
• PCIe 3.0 X4 bandwidth
• For PCIe 4.0 SSD, it will downgrade to PCIe 3.0 mode
• Support PCIe bifurcation function
• Support 2230/2242/2260/2280/22110 form factor
• The gap between the two NVMe slots is 3mm
• Regular profile bracket and low profile bracket

PCIe Bifurcation (PCIe Splitter)

• With ASM2821 PCIe Bifurcation function, PA20 can work with none PCIe Bifurcation motherboard;
• The disadvantage is that PA20 cannot support PCIe 4.0 and only support PCIe 3.0/2.0 features;
• The max bandwidth is PCIe 3.0 X4, which means 2 x M.2 NVMe SSD share PCIe 3.0 X4 bandwidth.

Soft RAID in Window 10

• When you find 2 separate M.2 NVMe SSD in Disk Management of Windows 10
• Right click the disk volume, which you want to setup soft RAID
• A pop-up window appears, click the option (Spanned/Striped/Mirrored)
• Noted: You can setup soft RAID in Linux/Mac/3rd party software also.

PCIE 3.0 X4 Full Speed

• Compatible with PCIe 3.0/2.0 motherboards, and install into PCI-Express X4 lane.
• To reach PCIe 3.0 speed, make sure your CPU and motherboard and PCIe SSDs are all PCIe 3.0 enabled.

M.2 SSDs Installation

• M.2 SSD head tilted at 30 degree angle, inserted into Key M interface
• The brass standoff snaps into the semi-circular position at the end of the M.2 SSD
• Secure the brass standoff from the back with screw

Packaging includes

1. PA20
2. 2 x M.2 Screw and Copper Stand
3. 8cm Low-profile bracket
4. Screws for bracket mounting to PC
5. Screwdriver
