As technology continues to improve and progress, 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 external 3.5” drive bay, maximizing the entire space of external 3.5” drive 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.
Complete Space Saver & Functionality
Utilizing its small form factor, The MB993SK-B is perfect for use in industrial PCs, SMB SFF servers, mobile DVR systems, or even home servers. The ability to house 3 x SATA SSD or HDD in a single external 3.5” drive bay makes it a valuable asset, as several different configurations can be implemented. With three drives, users can access all drives individually, making a perfect solution for systems that are constantly swapping between multiple OS drives or simply for storage in a small space. Moreover, in a system with three drives, it is ideal to have RAID 5 setup to achieve its fast performance along with data protection or use two drives for RAID 1 mirror data-protection and RAID 0 for doubling the transfer speed. The remaining third drive can be assigned as stationary OS drive or an extra hot-swappable bay. To keep cables from cluttering, a single SATA 4 power pin is used to ease installation. Save as much as space while maintaining the speed and maximizing the functionalities in a limited space, which is the beauty of the MB993SK-B.
Protect your Investments
Making sure your drives are in good hands and lasting as long as possible is carefully considered to any enterprise build and design. The MB993SK-B is capable of holding up in the harshest environments, with the rugged heavy duty metal construction in the entirety of the body and its smaller components. It can be used in various systems including: military and law enforcement deployment, as well as manufacturing conditions such as embedded control systems and factory automation systems. With the full metal design, the ToughArmor is perfect for industrial and medical devices that may require a flammability rating.
In order to fit three drives in a compact external 3.5” drive bay is challenging, the MB993SK-B is able to overcome this difficulty by carefully designing the EZ Slide Slim tray. With its durable and slim design, the trays are built with robust solid metal frames to securely mount and protect 5mm to 7mm height HDD/SSD, creating a reliable 2.5" hot swap bay for any standard SATA hard drives and SSDs. The EZ Slide Slim trays make drive interchangeability experience and maintenance completely hassle free.
The metal material used grants heat dissipation transfer from the hard drives to the mobile rack. Multi-Flow Technology (MFT) effectively routes air flow correctly for excellent passive cooling, via ventilation slots on the front, rear, top and bottom (in multiple locations). Lastly, Anti-Vibration Technology (AVT) and EMI Grounding are used to provide a stable environment for the hard drives or SSD’s used to perform at its best.
Versatile Utility & Security
The easy to read front LED indicators will indicate when a drive is ejected (no light), accessed (green), or has failed (red). Active Power Technology (APT) allows each drive LED to be on only when a hard drive is inserted into the enclosure. For drive security, the eagle-hook lock system on the tray makes sure your hard drives will not eject when not needed. Additionally, the 2 segment key lock provides extra protection to any physical theft of the hard drives, securing from any open and grab.

Upgrade your single or dual bay mobile rack system to the ICY DOCK MB993SK-B triple bay, full metal 2.5” SATA HDD/SSD cage
SSDs are clearly better than HDDs when it comes to performance. Since SSDs have become cheaper over the past few years and now 7mm height 2.5” SSD has reached 2TB storage capacity, it is quite possible that Solid-State-Drives may soon replace the traditional Hard-Disk-Drives.

If you are using a single or dual bay 2.5” mobile rack in your computer systems, it is a no brainer that you should, instead, go with ICY DOCK MB993SK-B triple bay full metal 2.5” HDD/SSD cage! The MB993SK-B fits 3 x 2.5” 7mm height SSD/HDD, occupies a single 3.5” front device bay only and allows you to squeeze up to total 6TB storage capacity without taking too much physical space from your system. All of this while retaining an easy to access cage for your drives that allows for easy drive swaps.

This is a perfect device for high-end computers and enterprise systems such as Gaming PCs, Image Processing Workstations, Industrial-PCs (IPC), mobile DVRs, mobile computers, embedded systems and other Small-Form-Factor (SFF) systems.
