Introducing ICY DOCK flexiDOCK MB511SPO-B, the world’s first tray-less 2.5” SATA SSD/HDD docking station enclosure for the 12.7mm Slim CD/DVD/Blu-Ray drive bays available on desktops, laptops, and workstation PCs. flexiDOCK makes it easy to expand the capabilities of your system with a second storage device, allowing you to effortlessly install and remove 2.5” HDDs and SSDs without the hassle of trays or screws. We designed the flexiDOCK to give you all the easy hot-swappable convenience of a docking station, with the durability and security of a fully enclosed mounting rack.

ICY DOCK’s MB511SPO-B uses a rugged full-metal enclosure meeting flammability requirements, ensuring that your drives are protected through at least 10,000 insertion/removal cycles. The enclosure has ventilation holes on the top and bottom of the enclosure for additional heat dissipation, keeping your SSDs cool under the heaviest of loads. A power switch allows you to shut down your drive without needing to eject it, saving power when the drive is not needed. FlexiDOCK is the perfect solution to anyone needing a high-quality, reliable drive docking system for their sensitive data, including video / photo editors, and IT professionals. MB511SPO-B is also compatible with any laptop that uses a 12.7mm optical disk reader, including models from Dell, HP, Acer, Gateway, Asus, Sony, Samsung, and MSI.

Designed for Slim ODD Bay

ICY DOCK’s flexiDOCK MB511SPO-B installs into your existing Slim 12.7mm CD / DVD bay, converting it into an easy hot-swappable docking station for your 2.5” HDD / SSDs. It replaces your existing 12.7mm optical disk reader, and has the exact same dimensions, screw hole locations, and port locations, and comes with all necessary screws for installation. MB511SPO-B is perfect for small-form-factor systems that require an additional drive beyond the usual mounting capabilities of your computer system. Because of this, the flexiDOCK is ideal for laptops, desktops, server racks, home theater PCs (HTPC), in-vehicle systems and portable system.

With the flexiDOCK MB511SPO-B you can consolidate your disk-based media onto an HDD or SSD, which have capacities nearly 500 times greater than a standard DVD.

Easy Hot Swap Docking

ICY DOCK’s flexiDOCK MB511SPO-B is designed to improve your workflow in any application that requires hot-swap by making it quick and easy to swap your drives. Thanks to the unique drive docking design, you can simply press a bare drive into the flexiDOCK and start your tasks. FlexiDOCK is completely tray-less, with tool-less drive installation saving the time it takes to screw drives in and out of trays and lowering potential labor costs in the event of drive failure.


Once a drive is inserted into flexiDOCK, an ejection button is revealed. The ejection button is a special designed two-segmented drive release mechanism that prevents accidental / unwanted drive ejection. To eject the drive, slide the ejection button to the left and then push inward to engage the drive release mechanism.


Whether you’re performing scheduled backups, or working on a media editing project that spans multiple SSDs, flexiDOCK makes it easy to swap your 2.5” SSDs & HDDs without needing to restart your computer. This means drive changes happen in seconds, not minutes, getting you back to work quicker without interrupting your workflow.

Packed with Features


ICY DOCK’s flexiDOCK MB511SPO-B surrounds your drive in a ruggedized metal housing with ample ventilation holes, designed to improve protection and maximize airflow, keeping drives cool under the heaviest loads.


To further prevent high-temperatures, MB511SPO-B includes a dust-cover that can be used when no drive is installed. This prevents dust from blocking airways and inhibiting cooling performance.

When a drive is installed, the eagle-hook mechanism is inserted into the drive’s screw hole, locking it in place and preventing it from falling out on systems prone to movement and vibration, such as laptops and in-vehicle systems.


FlexiDOCK’s ejection button features a key locking mechanism which locks the drive in place, protecting against accidental drive ejection and improving security in sensitive data environments.


When you’re done using your drive, flexiDOCK has its own power switch that lets you cut access to your drive at any time, without having to eject the drive. Shutting the drive off when not in use prevents additional wear from the system reading and writing to the drive.


An LED indicator gives you status updates at a glance, letting you know when your drive is in use and when it is safe to remove.


Optional EZConvert MB703M2P-B for M.2 SATA SSD


If you are looking to use a M.2 SATA SSD with the flexiDOCK MB511SPO-B, pair it with our EZConvert MB703M2P-B M.2 SSD to 2.5” form factor adapter featuring tool-less adjustable locker to secure your M.2 in place. To learn more about EZConvert MB703M2P-B please click HERE.


Compatible with Laptop Optical Bay (12.7mm height)

Replacing the CD / DVD drive on your laptop has never been easier with the flexiDOCK MB511SPO-B. Some laptops require an ODD bracket to be installed in the rear of the unit, and if this is necessary, it can be reused from the original CD / DVD drive before installing the MB511SPO-B.

Frequent Asked Questions

Q: I'm connecting SATA SSD to the MB511SPO-B, but the drives did not show up in my system. However, when I connect the SSD directly to the motherboard/add-on card, I can access the SSD without a problem.

A:It may be the SATA signal decreasing when connecting multiple bridges at the same time and causing the issue. Using a higher quality or shorter cable may solve this problem. However, if the problem occurs after replacing the cable, it may be the SSD/HDD you are using requires 12V power, which is not supported by MB511SPO-B. The MB511SPO-B is using the Slimline SATA power that does not carry the 12V power. Therefore, please avoid choosing the SSD/HDD that requires 12V power.



Please see the list below for the SATA drive that using the 12V power.


Seagate Nytro 1351 XA3840LE10063 / XA1920LE10063 / XA960LE10063 / XA1920LE10083 / XA960LE10083 / XA1920LE10103 / XA960LE10103
Nytro 1551 XA384ME10063 / XA1920ME10063 / XA960ME10063 / XA1920ME10083 / XA960ME10083 / XA1920ME10103 / XA960ME10103
IronWolf 110 ZA3840NM10001 / ZA1920NM10001 / ZA960NM10001


Note: The MB511SPO-B does not support SAS HDD/SSD, which also requires 12V power to be operated.
