StarTech 4 Bay Hard Drive Docking Station SATDOCK4U3E
If you need StarTech's 4-bay docking station, there's nothing better that can handle this many drives so easily. It can handle any 2.5-inch or 3.5-inch SATA drives from an old 300GB you may have lying around to your brand new 4TB drive. SDDs will work fine too, and although StarTech does not officially confirm or support this usage CD and DVD drives are apparently working on this unit. The internal interface will accept SATA 1.5, 3.0, and even 6.0 Gb/s drives, but keep in mind that the external eSATA interface will only support up to 3.0 Gb/s and your motherboard would need to support Port Multiplying if you want to see more than one of the four drives. On the other hand, there's also USB 3.0 (backwards-compatible with USB 2.0). You can hot-swap drives, but there's also an independent power button for each drive to be totally safe. Between all this functionality, powerful features, and total versatility, this dock is perfect for those work with a lot of drives and hardware.
