The ToughArmor MB699VP-B V2 is a Ruggedized Quad Bay Removable U.2 NVMe SSD Enclosure supporting PCIe 4.0 and fetching up to 64Gb/s data transfer rates through OCuLink (SFF-8612) interface. It is made out of heavy-duty full-metal construction and equipped with removable U.2 drive trays that simplify the time-consuming drive installation/removal process for easy drive maintenance. As PCIe 4.0 NVMe U.2 SSDs are prone to high temperatures under heavy load, the built-in dual 40x20mm cooling fans keep the drives at optimal temperatures and let you adjust the fan speed through the 3-speed fan control located in the rear of the enclosure.Superior PCIe 4.0 Performance To unlock the full potential of the PCIe 4.0 U.2 NVMe SSD, each drive bay uses a dedicated OCuLink (SFF-8612) connector to achieve the bandwidth rate of 64Gb/s, which is two times faster than PCIe 3.0 and 10 times faster than SATA standards. The extremely fast IOPS (Input/output operations per second) makes it an ideal solution for data-intensive applications such as autonomous driving, mobile automation, real-time forecast, film editing, and military computing. Removable Drive Tray Design Typically, NVMe U.2 SSDs are installed inside the computer case, which can be tough to reach when it requires maintenance. With the ToughArmor MB699VP-B V2, your drives are brought to the frontal 5.25" optical drive bay, where the U.2 SSDs can be easily accessed, making drive maintenance more efficient and straightforward process. The removable drive trays support any standard U.2 SSD from 5mm to 15mm drive height. Maximizing Cooling Performance Built-in with the dual 40x20mm cooling fans, the heat generates by U.2 SSD is further dispersed through the intelligently place ventilation holes throughout the entire enclosure. The dual cooling fans come with three fan speed settings: High, Low, and off. The user can choose the appropriate fan speed option to keep the drives at optimal operating temperatures. EMI Grounding Technology Grounding your drives are essential as swapping drives without the proper grounding may lead to hardware damage due to static shocks. With our innovative EMI Grounding Technology, once the drive is screwed onto the drive tray, the drive will be in a constant grounded state throughout the tray, housing, and computer system to ensure your drives are protected from static electrical surges safe during swapping.ToughArmor Protection Ensuring the enclosure can be relied upon for many years, the ToughArmor MB699VP-B V2 is capable of holding up in the harshest environment. It comes equipped with rugged, heavy-duty full-metal protection throughout the entire device and tray, making it perfect for industrial devices that may require a flammability rating. The outstanding build quality is suitable for various enterprise systems such as military and law enforcement industries, in-vehicle computers, and manufacturing conditions such as embedded control and factory automation systems. Packed with Features An LED status light built into the tray lets you know your drive is powered up and in use. The LED will shut off when no drives are installed to save power.
