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
1) 2 x M.2 PCIe 3.0 RAID Controller Adapter with PCIe Bifurcation
2) Soft RAID Configuration (Span, Stripe, Mirror Mode) in windows or Mac, it is not Hard RAID.
3) Asmedia 2812 chip, heatsink on chip for heat dissipation
4) PCIe 3.0 X4 bandwidth at max
5) Support 2230/2242/2260/2280/22110 size
6) For PCIe 4.0 SSD, it will downgrade to PCIe 3.0 mode
7) Support PCI-E bifurcation motherboard and None PCI-E bifurcation motherboard
8) Regular profile bracket and low profile bracket
Theoretical maximum speed
JBOD: 2 x M.2 PCIe 3.0 X4 SSD share PCIe 3.0 X4 bandwidth at Max
RAID 1: PCIe 3.0 X4 bandwidth at max
RAID 0: PCIe 3.0 X4 bandwidth at max
PCI-E Bifurcation
1) This PA20 can work with PCI-E bifurcation motherboard and None PCI-E bifurcation motherboard, that means PA20 can work with almost motherboards
2) For low-end motherboards, there is generally no PCIe bifuration function. But PA20 with Asmedia 2812 chip can work with low-end motherboards, and support M.2 PCIe JBOD/RAID 1/RAID 0
