Features: Expansion: The card allows you to expand your computer's storage capacity by adding- an NVMe M2 SSD to your system. This can provide more space for storing large files, games, and applications. High-speed data transfer: The card uses the high-speed PCI-Express (PCIe) X16 interface to ensure fast- data transfer rates between the SSD and your computer, allowing you to access and transfer large files quickly. RAID- support: The card supports RAID0 and RAID1 configurations, allowing you to optimize your storage performance- and efficiency. PCIe split card: The card is also a PCIe split card, which means- it can split the PCIe X16 signal to two PCIeX8 signals. This allows you to use the PCIe X16 slot on your motherboard- for other purposes while still using the card for storage expansion. Support 4-disk soft RAID-, and realize soft RAID- under WIN10. 4-disk has good-performance and RAID- stability. Adopted all-aluminum heatsink pad for better cooing performance-.
