Product Details
  • Enhance your system with the ToughArmor MB491SKL-1B, designed for seamless integration into any standard 3.5” drive bay, accommodating a robust 2.5-inch SAS/SATA HDD/SSD. Tailored for the most demanding settings, this enclosure boasts a MIL-STD-810G certified build for the body and tray, along with an IPX5-rated water-resistant cover, ideal for use in military, vehicular, and maritime applications, as well as autonomous and aviation technologies. Dual locks—a key lock plus a thumb screw—ensure double the security, guarding against both shocks and unauthorized access. With a removable caddy facilitating hot-swap capability, drive maintenance is effortless and uninterrupted, ensuring your mission-critical operations run without a hitch.
  • IPX5 Water-Resistant Front Cover
    Designed for harsh, moisture-prone environments, the IPX5-rated front cover protects against water jets from any direction, ensuring your data remains safe even when exposed to water. This feature is ideal for applications like field deployments in wet conditions or industrial settings where liquid exposure is a common hazard.
  • Double Security Lock System
    The ToughArmor MB491SKL-1B incorporates a dual locking mechanism - a barrel lock and a thumb screw lock - to secure the drive in place. This system prevents accidental drive ejection due to vibrations or bumps, offering an extra layer of security in mobile or turbulent settings.
  • Streamlined Hot-Swap Support
    The full-metal removable drive caddy supports hassle-free hot-swapping, significantly reducing downtime during hard drive failures—ideal for time-sensitive projects. It accommodates 5 to 15mm high HDDs or SSDs, creating a versatile 2.5” hot swap bay for any standard SATA/SAS drive. Additionally, the Anti-Dust Flap prevents dust from entering the device when the caddy is not installed, maintaining system cleanliness and functionality.
  • A Military-grade Durability
    Built with a rugged, all-metal chassis and drive caddy, the ToughArmor MB491SKL-1B 2.5-inch drive enclosure complies with military standards MIL-STD-810H 516.8 (Shock) and 514.8 (Vibration) and is built with the full-metal construction, making it suitable for military, aviation, and industrial applications where equipment must endure extreme conditions.
  • Packed with Features
    The ToughArmor MB491SKL-1B is feature-rich, equipped with a status LED that indicates power and access only when a drive is present, thanks to Active Power Technology.
  • Enhanced connectivity is ensured with 7-pin SATA data and 15-pin SATA power cables, featuring locking latches to secure connections and prevent accidental disconnections.

FAQ

Q: Does MB491SKL-1B support the new SATA 3.3 / SAS 3.0 Power Disable feature (PWDIS)?

A: The MB491SKL-1B does not support the SATA 3.3 / SAS 3.0 PWDIS feature. If you install the SATA/SAS HDD/SSD with PWDIS in MB491SKL-1B , the drive will not spin, and the system won't detect the drive. See the list below for known SATA/SAS HDD/SSD with the PWDIS feature.

 

While we recommend to avoid using the SATA/SAS HDD/SSD with PWDIS, you can use the methods below to disable the PWDIS feature physically if you already purchased the drive:

 

Method 1 – Using the Molex to SATA adapter or cable to disconnect the power to Pin 3 of the SATA power connector.

 

Molex to SATA Adapter   Molex to SATA Cable
Molex to SATA Adapter   Molex to SATA Cable

 

Method 2 – Placing Kapton tape on Pin 1-3 of the SATA/SAS power connector to isolate the 3.3V power, as shown below.

Please contact tech@icydock.com if the problem persists.


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.
