1 piece multi-function expansion card stable PCI-e signal separation array card 32gbps

Description: PCI-E X16 4-bay expansion card, 4*32Gbps full-speed signal, simultaneous expansion. The motherboard supports PCI-E split or PCI-E RAID function, and supports PCI-E 3.0 and 4.0 transmission protocols. 4-bay SSD array card with solid structure, thick PCB, and stable PCIEX16 interface to protect your important data. Supports 4-disk soft RAID, and realizes soft RAID under WIN10. The 4-disk consistency is good and the RAID is stable. No disk drop, no slowness, no blockage, imported high-power DC power chip to ensure stable operation of M.2 NVME SSD. The technology is mature and can be used with confidence. Only when four disks correspond to four LED indicators, the SSD access LED will light up and the SSD read and write LED will flash. Compatible with multiple systems, compatible with various mainstream operating systems, driver-free installation, plug and play ready to use (PS: Except for Win8/10 systems, other systems need to install drivers). Specifications: Name: 4 groups of NVME RAID PCI-E Size: 19. 5*13*3. 2CM product weight: product + baffle 73.6G Whole package weight: 119G Package contains: 1*array card 1*baffle 1*screwdriver 1 set Screw quantity Notes: Instructions for use: 1. The motherboard must support: the motherboard supports the PCI-E separation function, and can set the PCI-E X4X4X4 or 4X4 mode; supports the motherboard PCI-E RAID function; the ASUS motherboard supports the HyperM.2X16 expansion card function; different motherboards have different numbers of PCI-E Separate channels. Some motherboards have X8+X4+X4 PCI-E RAID. This motherboard's 4-bit M.2 card can only support 3 M.2 SSDs or devices, and the 2-bit M.2 card can only support 1 M.2 SSD or device. If you want to use this product normally, please choose the motherboard correctly. Many motherboards share PCI-E lanes. Make sure the motherboard supports PCI-E split functionality, but it doesn't recognize so many M.2 SSDs or devices. Please remove or replace other PCI-E devices, such as graphics cards, expansion cards, onboard NVME SSD, etc. A: For ASUS motherboards that support PCI-E separation, please refer to the following link https://www.asus.com/tw/support/FAQ/1037507B: For Huaqing motherboards that support PCI-E separation, please refer to the following link https://www .asrock.com/mb /spec/product.cn.asp?Model=ULTRA%20QUAD%20M.2%20CARDSupportList Server motherboards, X299 motherboards, and X399 motherboards all have split functions. 2. Requires CPU support, and the CPU must have enough channels. Generally, low-end CPUs do not have enough PCI-E lanes, so they may not be supported. When purchasing a CPU, you can refer to the motherboard's introduction to make the right choice.
