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 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, , and block, and import high-power DC power chip to the stable operation of M.2 NVME SSD. The technology is mature, and you can use it with . Only when four disks correspond to four LED indicators, the SSD access LED will , and the SSD read and write LED will flash. Multi-system compatibility, compatibility with mainstream operating , drive-free installation, plug-in and use (PS: other need to install drivers except Win8/10 system).
