Triple Bay 2.5" SAS/SATA HDD & SSD Mobile Rack For 3.5" Front Device Bay. As generation progresses, more and more advanced computer technologies are constantly improving. These improvements include maximizing enhanced functions in smaller and compact packages. This is why 2.5" solid state drives and hard drives are becoming more popular due to its low power consumption and space-saving benefits, which are superior to 3.5? SATA hard drives in almost every category. Combine with the extra bandwidth of the SSDs and the raw power of the processors; enterprises are able to accelerate their project-development process more efficiently. Since 2.5" SSDs and HDDs have smaller storage capacities compared to 3.5" hard drives, maximizing the storage density in limited spaces have become the most important task for many storage consulting firms; a task they often encounters. The ToughArmor MB993SK-B is designed specifically for systems with storage space limitations by fitting 3 x 2.5? SSD / HDD into a single 3.5" front device bay, maximizing the entire space of 3.5" device bay. On top of that, the MB993SK-B is built with heavy duty full metal construction which is commercially suitable for medical & military systems, government agencies, Industrial PCs, SMB workstations, VM workstations, mobile DVR systems, aerospace computers, automation systems and embedded systems.
