Introducing the Icy Dock ToughArmor MB607SP-B full metal quad bay 2.5" SATA 6Gbps hard drive or SSD hot swap rugged mobile rack cage for use in a single external 5.25" bay. The MB607SP-B is predicated off the incredibly popular ruggedized mobile rack MB994SP-4SB-1, while taking its general concept, but built with cost effective structure without sacrificing anything in the way of strength. For better compatibility, the original 4 pin power connector has been replaced with a more, popularly used, 15 pin SATA power connector, and reducing cable clutter. The MB607SP-B takes 4 x 2.5" SAS/SATA HDD/SSD from 5mm to 15mm height, and supports hot swap for quick and easy drive replacements. The single 40mm cooling fans has an additional 3-Mode Fan Speed control, allowing the best flexibility - Turn off / low when using SSD’s and high when using mechanical SATA hard drives. The MB607SP-B is constructed of rugged robust metal to survive the most demanding conditions making it a perfect storage upgrade kit for Medical & Military systems, embedded system, and industrial PC. Industrial Construction Ready Ensuring drive protection and longevity are the foundation of a high-quality data storage system design/build. The MB607SP-B is capable of withstanding the harshest environments due to its rugged heavy duty full metal construction from the outer shell to the inner trays. The ToughArmor’s full metal design is perfect for industrial and medical systems that may require a flammability rating as the full metal design is considered to already comply with most requirements. Versatile & Durable Drive Trays The MB607SP-B utilizes our EZ Slide Mini Trays, making drive interchangeability and maintenance completely hassle free. The trays are built using rugged full metal so that they are durable for many lifetimes, but will not weigh you down when transporting your data from system to system. The EZ Slide Mini tray is featuring a full range drive protection design; the top drive cover provides added protection while moving the drive. The trays are designed to accommodate 5mm, 7mm, 9.5mm, 12.5mm & 15mm drives giving you the ultimate universal 2.5" SAS/SATA drive support with hot-swap function. Multifunctional Applications Utilizing its small form factor, the MB607SP-B is perfect for use in small form factor system or system that requires multiple drives with limited physical space. With its high density drive design and limited number of 5.25" drive bays available, it is a perfect combo to create a RAID 5 or RAID 10 systems with ease. Also, it is built to function in the most demanding environments including military and law enforcement deployment, as well as manufacturing conditions such as embedded control systems and factory automation systems. The full metal design makes it ideal for placement in tough environments. Absolute Control of your 2.5" hard drive or SSD Bringing more utility to your hard drives or SSDs, LED’s are installed into the front of the mobile rack to provide individual drive status information at all times. Active Power Technology (APT) allows each LED and the cooling fan to be active only when a hard drive is inserted into the enclosure. A single 40mm cooling fan is placed on the rear panel, providing equivalent airflow throughout the entire cage. In addition, a 3-Mode Fan Speed Control has been added to be flexible in various situations, depending on your usage - you may need the fan to be at a higher speed, or completely off for silent operation.
