The FLEX-FIT Trio MB343SP is a very unique 3.5 to 5.25 front bay adapter. At first glance is of what looks like a simple 3.5 to 5.25 device bay adapter, but there is more than meets the eye. Weve created a device that utilizes a single 5.25 bay and converts it into 2 x 2.5 HDD/SSD slots and a 3.5 device or hard drive bay designed for tool-less drive installation. The FLEX-FIT Trio MB343SP pushes the envelope with its unique features and brilliant engineering. As a result, you get a beautifully crafted adapter that is sturdy, flexible and multifunctional. FLEX-FIT System One of the most unique features of the FLEX-FIT Trio MB343SP is the FLEX-FIT system, which provides users a higher level of flexibility for a 5.25 adapter that only an Icy Dock product can deliver. The FLEX-FIT Trio can store a 3.5 device or hard drive and an additional 2 x 2.5 HDD/SSD, IDE or SATA hard drives from 7mm 9.5mm height. Its both space efficient and cost effective since you wont be required to buy multiple brackets. The 3.5 bay can also take any standard 3.5 hard drive or SSD bracket, just slide in your 3.5 HDD or bracket and secure the drive with the side screw holes. Additionally, if you decided to install a 3.5 hard drive or device that doesnt have a front Input/output interface, you wont be left with an exposed slot. Weve thoughtfully designed the rear plate to snap off so you can insert it in the front panel slot to blend in with your system.Build Flexible Since the 3.5 bay takes both 3.5 hard drive and 3.5 device, there are many build options to choose from. For example, adding the ToughArmor MB992SK-B would give you two internal 2.5 slots with two external hot-swap 2.5 bays. Adding the EZ-Fit Lite MB290SP-B will give you four total 2.5 slots. The FLEX-FIT Trio is also compatible with USB 3.0 hubs, multimedia card readers and fan speed controllers in 3.5 form factor.
