Fast transmission: 20Gbps M.2 NVMe SSD solid state drive box is equipped with USB3.2 Gen2 Type-C interface, which can transfer 2G large files in 1 second, Theoretical transmission 20Gbps, measured read and write speed can reach 2000MB/S. Since different systems have different losses and speeds, the transmission speed . The M.2 solid state drive box is controlled by JMS586R main control chip, Better stability and compatibility. Effectively reduces the problem of hard disk heating. (Only support M.2 NVMe 2280 SSD). Large capacity expansion: This M.2 NVMe SSD enclosure can support up to 4TB capacity per disk, and 8TB storage capacity with 2 disks, providing you with greater capacity, so that work data, popular games, videos and can be stored anytime and anywhere. Aluminum alloy shell, fin groove design, built-in turbo fan and heat dissipation duct design, 4-layer heat dissipation system to the durability of the hard drive. Support 4 modes: LARGE mode, RAID1 mode, mode, PM MODE mode. Note:Only NVMe 2280 SSD are supported. (SSD Not inclued). The product has an intelligent sleep function. When there is no data transmission for 10 consecutive minutes, the hard disk automatically enter the sleep state to save energy. Any read and write operation can wake up the hard disk to resume normal operation. What computer port is required to achieve a transmission speed of 20Gbps?
