FlexiDOCK brings the quality and ease-of-use of a professional solution to the consumer market. With support for up to four 2.5" hard drives or SSDs, the MB524SP-B needs only a single 5.25" bay. Our new tray-less design has no doors, allowing for drives to be switched out in seconds. This is an improvement to many traditional hard drive docking stations that leave the drive sticking out and looking cluttered. The easy to press ejection button offers rapid drive ejection in a smooth, quick action. Individual power buttons for each bay allow drives to be turned on and off in an instant. The metal body with an air ventilating design works together with the adjustable 40mm fan to provide quiet operation while keeping your drives at optimal temperature.
