RaidSonic ICY BOX IB-RD2121STS

This little jewel from ICY BOX is a dual 2.5" to 3.5" drive caddy. It packs a huge punch with features and performance, allowing 2 x 2.5" SATA SSD/HDD to be converted to a 3.5" SATA form factor for use in most internal drive bays, backplanes, external enclosures, and server racks. It transforms the two drives into a 3.5" SATA drive with exact dimensions, mounting holes, and connection locations as a normal 3.5" drive.
But, it's not just a caddy though as it mimics a 3.5" drive with SATA and power connectors so it's easily inserted into a hot swappable drive cage, additionally it has an onboard RAID controller. The device uses a combined metal/plastic construction for durability and drive protection. Inside the case there is room for 2 x 2.5" SATA SSD or HDD fitting the standard 9.5 mm drive heights.
Thanks to the patented EasySwap feature, the door mechanism moves to connect the drives as the door is closed. This provides the user with peace of mind that the connection is solid. Also, the installation process is completely screw-less and tool-less, saving the user time when first installing the drives, as well as any necessary maintenance throughout the product's lifetime.
