The TowerRAID TR4U+ is a 4-bay storage enclosure for high capacity storage needs. With a built-in ventilating protective screen front panel, both units utilize a cable-less backplane-design to support up to four hard drives. Connecting to the USB 3.0 slot for 5Gb/s performance, 4 hard drives can be accessed at the same time using a single USB 3.0 cable. Backwards compatible with USB 2.0, the TR4U+ provides expandable storage with ease. With support of the latest 3TB hard drives, the TR4U+ is capable of having a total of 12TB in a single tower. Hard drive cooling is provided by a large 3.15” cooling fan located on the back of the unit. Supported in PC, MAC and Linux, the TR4U+ is an ideal solution for your storage needs.
Waiting for SATA III drive suppot
Pros: Looks like good unit, but as all USB 3.0 enclosures I have seen so far, this does not support SATA III 6GB/s drives!!! so if only supports 3GB/s input, how can output be anywhere near 5GB/s instead of less than 3GB/s?
Cons: No SATA III support. No eSATA 6GB/s support. USB 3.0 not fully supported.... 3GB/s MAX!!!

Pros: These are great towers. Whether you want to RAID it or just use it to access 4 drives for storage I recommend these highly. I bought this same tower about 6 years ago, with the only differance being mine was USB 2.0 only. I am still using the tower and the only thing that has changed over the years is the size of the drives it has housed.
Cons: The only issue I have is that in Vista when you set your computer to sleep the auto power switch does not shut the tower off. It only shuts the tower off when you shut down completely. Not sure this is a con but it would be nice if it shut down in sleep mode. Not a con but you want to be real careful and deliberate when changing the 2 dip switches on the back. 1 is the auto power and 1 is the RAID switch. If you have 4 drives full of data and flip the RAID switch accidently you will lose all your data. There is no warning stating that all data will be lost do you want to continue so take care if you are messing with these.
Other Thoughts: I have seen several people who claim "HIGH" tech knowledge slamming these towers with 1 egg reviews because their computers won't boot with the tower plugged in to their USB ports. These people are blaiming the manufacturer for their own computer illiteracy. My tower is plugged in and my computer boots up just fine because I don't have "Boot from USB device" enabled in my BIOS. If your box won't boot after plugging this tower in, enter BIOS and disable this function. If after doing this you still have issues contact the manufacturer and 9 times out of 10 they can help you solve your problem b4 you start leaving lousy reviews.
