Description: PCI-E X16 4-disk expansion card with 4* 32Gbps full-speed signal and simultaneous expansion. The main board supports PCI-E split or PCI-E RAID function, and supports PCI-E 3.0 and 4.0 transmission protocols. 4-disk solid-state drive array card, solid structure, thick PCB, stable PCIEX16 interface, care for your important data. Support 4-disk soft RAID, realize soft RAID under WIN10, 4-disk consistency is good and RAID is stable. Do not drop disk, slow , and block, and import high- DC chip to the stable operation of M.2 NVME SSD. The technology is mature, and you can it with . 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. Multi-system compatibility, compatibility with various mainstream operating systems, drive-free installation, plug-in and (PS: other systems need to install drivers except Win8/10 system).
