Features: USB 4.0 interfaces supports "one for three", connecting multiple devices at the same time, and transmitting data efficiently. Support M.2 SSDs solid States drive, NVME interfaces, fast reading speed, and provide stability guaranteeing. The high transmission speed of 40Gbps speeds up process of data replication and cloning. Four-position design, multiple hard disks can be installed at the same time, which is convenient for expanding storage space. Can be used for data backup, cloning, reading and other operations, suitable for individual users or office environment. Support M.2 SSDs solid States hard disk and NVME interfaces, which is widely applicable to all kind of hard disk brands and models. Four disks can be read at the same time, which supports 32T large capacity: four M.2 hard disks can be read and written at the same time, and the capacity can be expanded to 32TB, which can easily store massive data such as videos, files Equipped with 12V power adapter, the mini can't be underestimated, and the power supply is enough without damaging the disk. 40Gbps theoretical transmission chip scheme, the theoretical transmission value of a single disk can be as high as 16Gbps, and the clip/design material calls for second transmission without waiting. Specifications: Component: Aluminum Product model: DB2804N Color:Black Supported capacity: M.2 Single disk supports 8TB, with a total capacity of 32TB.
