Note: Light reflection and different displays may cause the color of the item in the picture a little different from the real thing. The measurement allowed error is +/- 1-3cm. 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 function, and supports PCI-E 3.0 and 4.0 transmission protocols. The technology is , and you can use it 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 Do not drop disk, , and block, and import high-power DC power chip to the stable operation of M.2 NVME SSD. Multi-system compatibility, compatibility with various mainstream operating systems, drive-free installation, plug-in and use (PS: other systems need to install drivers except Win8/10 system). 4-disk solid-state drive array card, solid structure, thick PCB, stable PCIEX16 interface, care for your important data. Support 4-disk soft , realize soft under WIN10, 4-disk consistency is good and is stable.
