The ICY DOCK FlexiDOCK MB522SP-B is the first professional 2.5 inch SSD / HDD docking designed for external 3.5 inch floppy drive bays. With the FlexiDOCK MB522SP-B, you can easily turn any legacy and often unused floppy drive bay into a dual bay hot-swappable drive slot that support any 2.5 inch solid state drive or 2.5 inch hard disk ranging from 5mm to 9.5mm height. All drive slots support full SATA 6Gb/s speed and compatibility with SATA's hot-swap function. Unlike a traditional external HDD docking station that makes the drives stick out from the device, the FlexiDOCK uses a smart drive ejection mechanism which allows the drives to be entirely inserted into the dock for a better system appearance and better drive protection. The easy to operate drive ejection button offers a smooth drive ejection action and is built in with the LED indicator for drive activity. The metal body and air ventilation design allows for efficient heat dissipation for the hard drives within the dock.
