The TowerRAID TR4U+B 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+B provides expandable storage with ease. With support of the latest 3TB hard drives, the TR4U+B 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+B is an ideal solution for your storage needs.
Decent for storage
Cons: *Can't use Windows "Dynamic Disks"
Other Thoughts: If you've got one of the newer 802.11ac routers with a USB 3.0 port and OpenWRT, it'd probably turn it into a decent NAS server. It won't work with Windows software RAID, but it works fine with LVM2 in Linux, and it seems able to saturate the USB 3.0 bus if you put fast drives in it.

Pros: Looks Nice, USB 3.0
Cons: No RAID and not worth it. Go for a Rosewill, but be prepared to work on a RAID setup with any of these external enclosures it can be a challenge. Had to return this one and pay shipping and restocking fees.
Other Thoughts: Please Someone make a better External RAID solution!

A little disappointed
Pros: Nice look. Space in between drives for better cooling. Fan spins slow enough so as to not be noisy. Interior construction is OK.
Cons: Main complaint is that the USB 3.0 is very unstable. Can't get through a few GB without it crashing the port requiring reboot. I've bought other cases from San Digital and the case has always been made from solid aluminum, but this one has a cheap sheet metal body.

Pros: - Non-Expensive
Cons: - A bit on the noisy side.
Other Thoughts: The reason I am giving thise 4 star out of 5 star is not because of the product, but because of the reality of using software RAID with USB hard-drives

Pros: I have 6 of this model and over 30TB worth of storrage. I have two units running on ESATA 300 and 4 units running on USB dedicated adaptors. I have never had a problem accessing data on either the ESATA or USB3.0 interfaces.
Cons: Bad Fans. After 6 months one of the fans started to gurrrr!
Other Thoughts: Over all, I think you would be hard pressed considering the cost of these RAID enclosures to to better elsewhere. The cost of a $10 fan is nothing and plugs right in the same connector, no big deal. Operationally, they have been perfect. The RAID Rebuilds reliably also. Not hot swap.
