The ToughArmor MB834MK-B V2 is a robust 2 x M.2 NVMe SSD hot-swappable enclosure that fits into a single external 3.5" drive bay of a computer system. It supports PCIe 4.0 with data transfer rates of up to 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 for easy drive swaps 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 high-efficiency aluminum heatsink, which, along with a series of ventilation openings around the enclosure, ensures that your SSDs maintain optimal temperatures. As part of ICY DOCK's most robust product line, the MB834MK-B V2 features a full metal construction with metal locks for maximum protection.
