Introducing the Icy Dock ToughArmor Series MB994SP-4S Quad Bay 2.5" SAS / SATA SSD & Hard Drive Hot Swap Mobile Rack Cage for use in a single 5.25" device bay. This product is constructed of heavy duty metal to hold up in the toughest of conditions. It includes ventilation slots on the front & back for maximum airflow to keep both SATA and SAS drives running cool, and an LED is placed on the front of each drive tray to give the user drive status at all times. Dual 4-pin power connectors are used to ensure a consistent power supply to all 4 drives, whether they are low power SSD’s or power hungry 15000 RPM SAS drives. Also included are dual 40mm cooling fans to keep the drives running in at optimal temperatures in even the most intense applications. This is a device commercially designed for: Medical & Military systems, Media servers, IPCs, HTPC, and All-In-One computers, approved & used by Tier 1 companies.

The MB994SP-4S is constructed of full metal to hold up in the toughest of conditions. It includes ventilation slots on the front and back for maximum airflow to keep your drives running cool, and an LED is placed on the front of each drive tray to give the user drive status at all times. The ToughArmor's full metal design is also perfect for industrial and medical devices that may require a flammability rating as the full metal material is considered to already comply with flammability requirements.

The MB994SP-4S utilizes our brand new EZ Slide Mini Trays, making drive interchangeability and maintenance completely hassle free. The trays are built using full metal so that they are durable for many lifetimes, but will not weigh you down when transporting your data from system to system. And featuring a full cage design, the added top drive cover provides added protection while moving the drive. The trays are also designed to accommodate 7mm, 9.5mm, 12.5mm, and 15mm drives giving you the ultimate universal 2.5" hot swap bay.

Utilizing its small form factor, The MB994SP-4S is perfect for use in industrial PCs, servers, or any small form factor case where 5.25” bays are limited and large drive capacity is needed, especially compact RAID 5 systems. 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 heavy metal design makes it ideal for placement in rugged environments.

"The MB994SP has many things going for it. Not only is a sleek looking solution to keeping all your 2.5” drives in one convenient location, but it also cools them (if they’re mechanical) and keeps them safe."

"The MB994SP-4S has excellent build quality, is easy to install and swap drives, and has good cooling. Other than the fact that drives cannot be locked in for security, it is a no-compromises device and I give it my full recommendation."

"If you looking for more expansion capability in your SFF case (or even a full tower case), look no further than the Icy Dock MB994SP-4S."
Launch Date: Aug 2010

"There is no doubt that Icy Dock MB994SP-4S is a unique and exciting product since it can accommodate up to four 2.5" SATA/SDD/SAS HDD at the same time with only consuming a single slot of 5.25" external drive bay of a chassis. 2.5" HDD is seldom being used in desktop system due to higher cost than 3.5" HDD and its limited supportability by most of the desktop chassis. However Icy Dock MB994SP-4S has just broken the impossibility by supporting quad 2.5" HDD at the same with; ideal for those are looking for frequent & complicated data transferring, data back up."
