Introducing the flexiDOCK MB830SP-B professional removable HDD docking enclosure. It offers the ability to hot-swap up to 3 x 3.5-inch SAS and SATA hard drives using only two 5.25-inch external drive bays. The 100% tool-less and tray-less design means drive installation and removal happens by hand in seconds, not minutes, saving valuable time whether you’re a home user, computer forensic specialist, computer repair technician, HDD duplicator or a media workstation editor. A strong full-metal body ensures a long product life, better heat dissipation and keeps your sensitive drives protected at all time. To prevent overheating damage in active environments, the large user-adjustable cooling fan works together with the well-ventilated metal chassis to provide ample cooling performance.
Made for Hot-Swap
Installing or removing drives in a computer system requires opening up the case, using tools, and plugging in cables, a process which can take several minutes for a single drive. If you often swap drives, flexiDOCK is a better solution. The spring-loaded door allows bare hard drives to be pressed in directly, without tools, screws, trays, or any additional work. The wide front bezel allows drives to be easily removed by hand, pulling drives out in just a matter of seconds and saving valuable time. The simple drive removal system allows drives to sit flush with the computers front panel, reducing clutter and protecting your sensitive drives from environmental hazards.

Built with Security

flexiDOCK MB830SP-B’s full-metal enclosure protects sensitive hard drives from external forces, providing a longer life span for your drives.

Maximum Cooling Efficiency

The heat dissipating properties of the enclosure, combined with the amply placed ventilation holes, provide excellent passive cooling abilities.

Customizable Cooling Options

For additional cooling performance, flexiDOCK uses a large 80mm cooling fan with easy access fan speed control, allowing you to pick the best cooling profile for your application. Use a low setting for quiet operation in a home computer or NAS device. Turn the fan up to high for intensive applications, to keep drives running at their optimal safe temperatures.
Packed with Features
To prevent the buildup of dust and debris, which can clog internal connectors and lead to damage, each bay is covered with a spring-loaded dust cover. When installing a drive, simply press the drive in, and the dust cover effortlessly tucks away into the enclosure.

The drive door not only acts as a dust flap, but it also works as a drive guiding mechanism. When inserting the drive, it pushes the door inward to become paralleled with the metal side panel and acts as drive guiding pegs and anti-vibration kit. It provides better drive stability and compatibility for different drive heights, and absorbs vibration caused by mechanical hard disk drives.


Each bay features its own LED drive indicator light, to notify you of any drive activity. The soft blue LED is easy to see, but not too bright for dark environments.

flexiDOCK MB830SP-B supports SATA data and power cables with locking latch designs, and comes with 3x locking latch SATA data cables. Once these cables are connected, they’ll lock into place and stay that way, protecting against accidental disconnection.
All three drives are powered by only two power cables, which reduces cable clutter. Fewer cables not only improves aesthetics, it improves airflow within your computer, further reducing temperatures of critical components.

Optional 2.5" to 3.5" SSD/HDD Converter


If you would like to use 2.5" drives with this device, the optional EZConvert MB882SP-1S-3B is an unique converter that is able to transform your 2.5" drive into a 3.5" HDD form factor within seconds without any tools.

Frequent Asked Questions
Q: Does MB830SP-B support the new SATA 3.3 Power Disable feature (PWDIS)?

A: The MB830SP-B does not support the SATA 3.3 PWDIS feature. If you install the SATA HDD/SSD with PWDIS in MB830SP-B, the drive will not spin, and the system won't detect the drive. See the list below for known SATA HDD/SSD with the PWDIS feature.

ST3000NM0035 ST2000NM0085


Note: the SAS hard drive or SSD does not use the Pin 3 of SATA power connector for PWDIS feature and compatible with MB830SP-B.


While we recommend to avoid using the SATA 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 power connector to isolate the 3.3V power, as shown below.

ICY DOCK MB830SP-B & MB882SP-1S-3B Review


"Small computer chassis often have the disadvantage that they can only hold a few hard disks, but mainboards have many connection options for hard disks and the chassis can often hold optical drives, the importance of which has declined considerably in recent years. This is exactly where the Icy Dock 3.5” Drive Bay MB830SP-B is used for installation in two 5.25” drive bays, which can accommodate up to three 3.5″ HDDs......"
