Quad M.2 NVMe SSD Host Adapter with PCIe Bifurcation Function
- Add 4 x M.2 NVMe SSD (M-Key) onto a single PCIe X8 host adapter, so you can access 4 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 X8 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 ASM2824 PCIe Bifurcation function, PA40 can work with none PCIe Bifurcation motherboard;
- The disadvantage is that PA40 cannot support PCIe 4.0 and only support PCIe 3.0/2.0 features;
- The max bandwidth is PCIe 3.0 X8, which means 4 x M.2 NVMe SSD shares PCIe 3.0 X8 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 set up soft RAID
- A pop-up window appears, click the option (Spanned/Striped/Mirrored)
- Noted: You can set up soft RAID in Linux/Mac/3rd party software also.
PCIE 3.0 X8 Full Speed
- Compatible with PCIe 3.0/2.0 motherboards, and install into PCI-Express X8 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 a 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 a screw
Packaging includes
- PA40
- 4 x M.2 Screw and Copper Stand
- 8cm Low-profile bracket
- Screws for bracket mounting to PC
- Screwdriver
