The ToughArmor MB834MK-B V2 is a robust 2 x M.2 NVMe SSD hot-swap enclosure that fits into a single external 3.5" bay of the computer system. It supports PCIe 4.0 with data transfer rates of 64 Gbps via the 2 x SlimSAS 4i (SFF-8654) interface and accepts all standard M.2 drives with lengths ranging from 30 mm to 110 mm (2230, 2242, 2260, 2280, 22110). The enclosure simplifies the process of installing or removing M.2 NVMe SSDs by using removable drive trays with tool-less adjustable M.2 locks, allowing drives to be easily swapped at any time without the need to open the computer case or deal with drive mounting screws. Additionally, each drive tray is equipped with a highly efficient aluminum heatsink, which, along with a series of ventilation holes around the enclosure, ensures that your SSDs maintain optimal temperatures. As a member of ICY DOCK's most robust product line, the MB834MK-B V2 features a full metal construction with metal locks for maximum protection.
