Data security is essential for any business. For military and medical settings, both software and hardware security is necessary to protect sensitive data. The ToughArmor MB994SK-1B is the first ToughArmor cage that features individual steel locking mechanism for each bay. You'll put your mind at ease. knowing that your data has extra layer of the protection, and safe inside an strong full metal enclosure. The ICY DOCK ToughArmor MB994SK-1B takes 4 x 2.5" SAS/SATA HDD/SSD from 7mm to 15mm height, and supports Hot Swap for quick and easy drive replacements. The unit is constructed of robust metal to survive the most demanding conditions, dual 40mm cooling fan with ventilate slots on the front/rear help to cool your drives 24/7. The MB994SK-1B is commercially designed for Medical & Military systems, IPC, enterprise, and industrial settings.

Indestructible and Secure

Ensuring drive protection and longevity are the foundation of a good system design/build. The MB994SK-1B is capable of withstanding the harshest environments due to its heavy duty full metal construction from the outer shell to the inner trays. The ToughArmor's full metal design is also perfect for industrial, military and medical systems that require a flammability rating as the full metal design is considered to already comply with most requirements. The metal construction dissipates heat from the hard drives to the backplane cage essentially acting as a heat sink to keep drives cool. We've also added a new locking mechanism that provides an additional layer of security by preventing drive access from unwanted intruders or meddlers. In order to keep it compact, we have embed a custom made steel lock mechanism to the EZ Slide Mini tray, so each bay has it's own individual lock allowing the user to lock only certain desired drives. Best of all, the EZ Slide Mini tray with lock is backward compatible with any ToughArmor uses EZ Slide Mini tray system, so compatibility will not be an issue.


EZ Slide Mini Trays for EZ Accessibility

Using the EZ Slide Mini trays makes drive interchangeability and maintenance completely hassle free. The EZ Slide Mini trays are designed to accommodate 7mm to 15mm height hard drives and SSDs. The built-in drive protection cover added stability during the drive insertion and provides extra protection to the drive.


Huge Capabilities in a Small Form Factor

Utilizing the standard 5.25” bay form factor, the compact design allows the enclosure to be used in various applications, catering to a wide audience. The MB994SK-1B can be setup as JBOD cage or in a RAID configuration with RAID card such as a high performance RAID 0 array for maximum capacity and IOPS, RAID 10 for both safety and performance, or using RAID 5 for data protection, all while taking up just a single 5.25” device bay. The Tougharmor MB994SK-1B supports both SATA and SAS interface, and supports both hard drive and SSD, so whether you want to run four 2TB SATA HDD in RAID 0 or four 15k rpm SAS HDDs in RAID 5 you wouldn’t be limited by the drive selection, that's the beauty of the ToughArmor MB994SK-1B.


Made for Builders

The MB994SK-1B 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 systems. It is built to function in the most demanding environments including military, medical system and law enforcement deployment, as well as manufacturing conditions such as embedded control systems and factory automation systems. The heavy metal design with key lock function makes it ideal for placement in rugged environments.
