Product Introduction

Introducing the Icy Dock ToughArmor MB994SP-4S Full Metal Quad Bay 2.5" SATA 6Gbps Hard Drive/SSD Hot Swap Mobile Rack Cage for use in a single external 5.25" bay. The dual power connection is designed for SATA and SAS drives with higher power needs, allowing all drives to receive the needed power. The dual 40mm cooling fans allow for airflow throughout the drive cage, maintaining optimal temperatures. Furthermore, this device utilizes Active Power Technology, so that the device only power up if there are drives installed.
The MB994SP-4S is constructed of rugged 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 rugged full metal design is also perfect for industrial and medical devices that may require a flammability rating as the rugged full metal material is considered to be already compliant with flammability requirements.
The MB994SP-4S utilizes our EZ Slide Mini Trays, making drive interchangeability and maintenance completely hassle free. The trays are built using rugged 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 5mm, 7mm, 9.5mm, 12.5mm & 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 gaming PCs, small form factor cases where 5.25” bays are limited and large drive capacity or SSD’s are needed. This also will benefit 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 rugged heavy metal design makes it ideal for placement in tough environments.
To maximize cooling efficiency, the MB994SP-4S features a design that places two PCBAs in a lateral orientation. This strategic arrangement prevents the airflow from being obstructed by vertically positioned PCBAs, which can impede heat dissipation. Consequently, the MB994SP-4S is exceptionally well-suited for use in high-temperature system environments, or in conjunction with high-RPM 2.5” SAS hard drives or high-IOPS 2.5” SAS/SATA SSDs. It ensures peak and steady performance under even the most demanding operational conditions, while also prolonging the life of your drives.
Enhance Security with Our Lockable Drive Tray

If your application demands added physical security to protect valuable data from theft, you can upgrade with the compatible lockable drive tray MB994TK-B for an instant security boost to your MB994SP-4S. Alternatively, if you prefer a solution that includes lockable drive trays by default, the MB994SK-1B is available for purchase. For inquiries about large volume orders, please contact our sales team at sales01@icydock.com.
Make ToughArmor On-The-GO! With MB991U3-1SB

To access your data outside of your system or in a remote location, the ToughArmor MB991U3-1SB is the way to go about. The drive tray slot of MB991U3-1SB is compatible with a variety of ToughArmor drive trays including the ToughArmor MB991, MB992, MB994, MB996 and MB998 series. This allows existing ToughArmor users to access their internal drive externally without opening up the case. It is a great tool for an individual drive diagnostic test. If you need to do a safe data erase or just simply expending system storage capacity, just remove the tray from the internal ToughArmor unit and insert it in the MB991U3-1SB to perform individual tasks externally with USB 3.0 interface. Best of all, the MB991U3-1SB uses USB bus-powered and it does not require a power adapter to operate. Simply connect the USB cable to any system and you are ready to go.

FAQ

Q:The mounting screws for the device seem to be too short to secure the device onto my system, what should I do?

A: For computer cases that have a thick metal sheet, the included mounting screws (M3*2.5L) may not fully secure the device. Please use longer screws (M3*4L) to secure the device or contact us at tech@icydock.com for replacement screws.

Q: I feel that the drive tray's upper and lower metal spring is stuck when inserting the drive tray. What should I do?

A: Remove the drive tray from the enclosure and reinsert the tray without putting excessive pressure on the metal mesh sheet in front of the tray. Excessive force on the front metal mesh sheet may bend the top and bottom metal spring, causing difficulties when inserting the drive tray. Therefore, please do not forcingly insert the drive tray when this happens as it may cause damage to the metal spring.

Please DO NOT put excessive pressure on the metal mesh sheet as shown

Q: After installing a drive in the MB994SP-4S, the LED indicator does not flash orange when accessing data but remains solid green. What could be the cause and what is the solution?

A: The MB994SP-4S is designed according to the standard signal specifications for SSDs/HDDs and is compatible with the vast majority of drives on the market. However, differences in voltage settings for some specific drives may cause the LED indicator to remain solid green during data read/write operations. This situation will not affect the performance or lifespan of the hard drive, so please use it with confidence. If the hard drive reading indicator light is a necessary feature, consider using other brands and models of drives. Additionally, refer to the list below reported by users of drives that have this issue to avoid using those models with this product.
