No data storage enclosure is complete without reliable drive connections, and proper drive protection. Many enterprise applications rely on their data to run their business, and any major downtime or data loss can be crippling. The ToughArmor MB998IP-B utilizes a rugged full-metal removable drive enclosure, and the latest in drive connection technology, to bring you the best in stability, speed, and reliability. For your dense data storage needs, it holds an unprecedented 8x 2.5" SAS / SATA hot-swappable drives with 5mm-7mm height, all in a single 5.25" bay. The two Mini-SAS HD (SFF-8643) connectors at the rear of the unit makes it easy to connect to a modern RAID card and reduce cable clutter, while offering additional bandwidth and reliability over SATA connections. The dual 40mm user-controllable cooling fans and ventilated metal case keep your drives running longer, even under the toughest of loads. The fan has three modes the user can set; high, low, and off. The ToughArmor MB998IP-B features a rugged heavy duty full-metal enclosure designed to handle I/O intensive applications such as data mining, information retrieval, video processing, HPC, VDI, cloud service, database, and server.
