We’ve previously seen SATA hard disk multi-function docks in the past, but how many of those allow you to dock up to three 3.5”drives? The SATA HDD Multi-Function Dock is capable of supporting up to three SATA 2.5″/3.5″ drives up to 2TB. The accessory also includes a built-in multi-card reader and also an additional two USB ports. The dock currently supports both Mac and PC and will set you back $55.
